10 Best Small Form Factor Gaming PCs (October 2026) Authentic Reviews
A gaming PC that disappears under your monitor used to mean compromising on everything that matters. That is no longer true. The best small form factor gaming PCs in 2026 pair desktop-class memory and storage with laptop-class processors, and the gap between a tiny box and a full tower has narrowed to a few hundred milliseconds of load time and a little more fan noise.
I have spent the last several months working through this category, reading spec sheets, digging into owner reports, and watching how these machines behave outside of a spec sheet. What I kept coming back to is that there is no single best small form factor gaming PC. There is a best one for esports, a best one for an eGPU build, a best one for a silent desk, and a best one for a homelab. This roundup names all ten.
Here is the honest framing before we get into the picks. Every machine below runs integrated AMD Radeon graphics, not a discrete desktop GPU. That means 1080p esports at high refresh rates, older titles, indie games, emulation and light 1080p AAA settings with upscaling are all fair game. It also means anyone expecting ray tracing at 1440p should skip this entire list and look at our guides to gaming PCs for 4K and graphics cards that actually fit in SFF cases instead.
Two more things shaped this ranking. First, upgradability, because soldered memory is the single most permanent decision you make on a mini PC. Second, noise, which is the number-one complaint in every small form factor forum we checked. If a machine had a fan mode published in dB, we weighted it. Where nothing was published, we said so rather than guessing.

1. GMKtec K11 – Ryzen 9 8945HS With Native OCuLink And The Most Headroom
- Ryzen 9 8945HS with 8 cores and 16 threads at up to 5.2GHz
- 32GB dual-channel DDR5-5600 lifts minimum frame rates in open-world titles
- Native OCuLink runs at PCIe x4 giving eGPU builds more bandwidth than Thunderbolt
- Dual Intel i226V 2.5GbE NICs plus WiFi 6 and Bluetooth 5.2
- Storage expands to 8TB across dual PCIe Gen4 x4 slots
- Radeon 780M is the gaming ceiling without an external GPU
- Some buyers need a BIOS and microcode update straight after unboxing
- Rear port count is limited for heavy peripheral setups
Ryzen 9 8945HS to 5.2GHz
Radeon 780M at 2800MHz
32GB DDR5 and 1TB SSD
OCuLink plus dual 2.5GbE LAN
The K11 is the machine I keep coming back to, and the reason is not the processor. The Ryzen 9 8945HS is excellent, but eight Zen 4 cores at up to 5.2GHz are no longer unique in this chassis size. What is unique is everything around the chip.
Dual-channel DDR5-5600 is a 17 percent uplift in memory bandwidth over the 4800MHz kits that used to ship in this class, and owners consistently point out what that does for the Radeon 780M, which is bandwidth-sensitive. In open-world games the practical effect is a higher floor under the frame rate rather than a higher peak. I have also found that 32GB of DDR5 here is real, dual-channel, socketed memory rather than a soldered LPDDR package pretending to be 32GB.
Then there is OCuLink. Most competing boxes list OCuLink on the spec sheet and ship it as an M.2 adapter card that costs you a storage slot. The K11 has it native, running at PCIe x4, which is roughly twice what Thunderbolt 4 delivers in practice. Pair this with an external GPU and you have a compact box that borrows a desktop card for a few hours when you need it, then goes back to being a small quiet machine on your desk.
The networking is the quiet flex. Two Intel i226V 2.5GbE ports means this can sit on a firewall, a router, or a small storage server without a USB adapter, and WiFi 6 with Bluetooth 5.2 covers the cases where you do not want to run cable. Storage starts at 1TB on PCIe 4.0 and reaches 8TB across two Gen4 x4 slots. Cooling is dual-fan and published at 35dB in Quiet mode, with three BIOS power profiles to pick from.
Who The K11 Fits Best?
This is the box for someone who is not sure yet. If you want integrated graphics today and an external GPU in two years, the K11 gives you both. Owners who pair it with an eGPU over OCuLink report it is a genuinely workable 1080p 60fps setup, and the x4 link means you are not leaving half the GPU’s bandwidth on the table.
It is also the natural choice for anyone running this as a small server or a heavy multi-hypervisor box, given the dual NICs and the RAM headroom to 128GB.
Where The K11 Falls Short?
The Radeon 780M is the ceiling. Without an external GPU, this is a 1080p machine, and a 1080p machine with settings adjusted. Owners who expected console-level AAA performance from the marketing photos are the source of most of the one-star feedback in this category generally, not just here.
One practical warning: check for a firmware update during setup. Some buyers report needing a BIOS and microcode update before the machine settles into its rated performance. It is a five-minute job, but it should happen before you benchmark anything.
2. GEEKOM A9 Max – 12 Cores, Radeon 890M And The Longest Warranty Here
- Ryzen AI 9 HX 470 with 12 cores
- 24 threads and 86 TOPS of AI acceleration
- Radeon 890M reported up to 90 FPS in Cyberpunk 2077 and 130 FPS in F1 24 with upscaling
- 32GB DDR5 expands to 128GB with dual Gen4 NVMe slots to 8TB
- All-metal chassis with IceBlast 3.0 copper cooling stays quiet under load
- 3-year warranty plus Windows Pro for Hyper-V work
- Costs far more than every other mini PC in this roundup
- Limited USB-A ports mean most owners need a powered hub
- Fan noise climbs under sustained heavy workloads
Ryzen AI 9 HX 470 12C/24T to 5.2GHz
Radeon 890M
32GB DDR5 and 2TB SSD
WiFi 7 with 3-year warranty
The A9 Max is the most capable integrated-graphics machine in this list and the most expensive by a wide margin. If the price is not the deciding factor, this is as much integrated graphics performance as a small box currently delivers.
Twelve cores and 24 threads on a Ryzen AI 9 HX 470 running up to 5.2GHz, paired with Radeon 890M graphics, is a different class of silicon from the 8-core parts in most of this roundup. Owners report up to 90 FPS in Cyberpunk 2077 and 130 FPS in F1 24 with upscaling enabled. That is playable 1080p gaming from a box with a listed footprint of just over 5 by 5 inches and a height under 2 inches.
Memory is 32GB of DDR5, expandable to 128GB across dual Gen4 NVMe slots for up to 8TB of storage. The 86 TOPS of AI acceleration, including a 55 TOPS XDNA 2 NPU, is not a gaming feature, but it is the reason this machine keeps showing up in local AI workloads alongside gaming.
Connectivity is the best in the roundup: dual 2.5GbE LAN, WiFi 7, Bluetooth 5.4, TPM 2.0, two HDMI 2.1 and two USB4 outputs driving four displays at up to 8K. The all-metal chassis uses IceBlast 3.0 cooling with a copper heatsink and dual heat pipes, and the 3-year warranty is three times the 1-year norm most brands in this category offer.
Who The A9 Max Fits Best?
Buy this if you want one machine to do gaming, emulation, video work and local AI without a second machine on the desk. Owners running multiple Hyper-V virtual machines on a Windows Pro license describe exactly that setup working, and the 32GB base can grow to 128GB later.
It also suits anyone with an eye on the 8K display path, since dual HDMI 2.1 plus two USB4 outputs cover four panels at up to 8K.
Where The A9 Max Falls Short?
The price is the entire problem. It sits above every other machine here by a distance that a 4.4 rating and 649 reviews do not make easier to justify, and if gaming is your primary use, a large part of the money is buying AI silicon you may never touch.
Two smaller issues. USB-A port count is low, so expect to add a powered hub. And fan noise rises noticeably under sustained heavy workloads such as multiple VMs, and gets louder again if the unit is laid flat instead of stood on its side.
3. BOSGAME P3 Pro – Zen 4 Gaming Silicon With Memory You Can Actually Replace
- Ryzen 9 7940HS delivers 8 cores and 16 threads at up to 5.2GHz
- 16GB DDR5-5600 is upgradeable to 64GB unlike most soldered rivals
- Second SSD slot plus dual 1000Mbps Ethernet for routing or server use
- 3-year parts warranty on a value-tier machine
- Triple display output via HDMI
- DisplayPort and USB-C
- No operating system ships in the box
- Only four USB ports limits peripheral expansion
- Radeon 780M is the limit for modern AAA gaming
Ryzen 9 7940HS 8C/16T to 5.2GHz
Radeon 780M at 2700MHz
16GB DDR5 upgradeable to 64GB
1TB PCIe 4.0 NVMe
The P3 Pro is the recommendation I make most often, and the reason is a single spec line: the 16GB of DDR5-5600 is upgradeable. It is socketed memory in a machine that costs less than most soldered rivals, which means a 32GB or 64GB configuration is a cheap future upgrade instead of a whole new computer.
Underneath sits the Ryzen 9 7940HS, 8 cores and 16 threads on a 7nm Zen 4 design boosting to 5.2GHz, paired with Radeon 780M graphics running at up to 2700MHz. That combination handles 1080p esports titles comfortably and lighter AAA games with settings turned down. Note that the listing and the spec sheet disagree on maximum memory, one saying 64GB and the other 96GB, so verify against your BIOS before planning a large upgrade.
Networking is the quiet strength: dual 1000Mbps Ethernet ports mean this can act as a router or a small server, and WiFi 6E with Bluetooth 5.2 covers everything else. Storage is 1TB of PCIe 4.0 NVMe with a second SSD slot for expansion. Output is triple display through HDMI, DisplayPort and USB-C, and the machine supports Windows 11, Ubuntu and Linux.
What you give up for the price is ports. Four USB ports is genuinely limiting with a keyboard, mouse, controller and a headset all plugged in, and a USB 3 hub is close to mandatory. The warranty is 1 year on the machine and 3 years on parts, which is a better split than most competitors manage.
Who The P3 Pro Fits Best?
This is the pick for a first gaming PC on a small desk, a shared household where two people need rigs, or a student machine. At 467 reviews with 71 percent five-star ratings, it also has a larger review pool than several pricier boxes here, which means the 4.4 average is more meaningful.
If you plan to run Windows and a heavy game library, buy it with an SSD you like rather than whatever ships in the box.
Where The P3 Pro Falls Short?
No operating system is included, so you are adding Windows or a Linux install yourself before anything else. That is not a problem for anyone comfortable with it, and it does keep the machine flexible for Linux and homelab use.
Driver support on Linux is less certain than on Windows according to owners, so if you plan to run anything beyond Ubuntu, check your distribution’s support first. And the four-port USB count is the day-to-day irritation that never goes away.
4. GMKtec K12 – Three M.2 Slots And Fully Implemented USB4
- Ryzen 7 H 255 gives 8 Zen 4 cores
- 16 threads and AVX512 support
- Three M.2 2280 slots allow up to 24TB of total storage
- OCuLink plus fully implemented USB4 with PCIe tunneling for eGPU and Thunderbolt 4 use
- Dual 2.5GbE LAN with WiFi 6E and Bluetooth 5.2
- Radeon 780M handles AV1
- AVC and HEVC encode-decode
- Firmware lacks S3 sleep and offers only modern standby
- TPM can fail or lock up on resume
- requiring a reboot
- External USB port count is lower than some rivals so heavy peripheral users need a dock
Ryzen 7 H 255 8C/16T to 4.9GHz
Radeon 780M 12 CU
32GB DDR5 and three M.2 slots
OCuLink plus dual 2.5GbE LAN
The K12 is the connectivity king of this roundup, and the difference comes down to a word in the spec sheet: fully implemented. USB4 here carries PCIe tunneling, which means it works as an eGPU link and not just as a fast USB port. Combined with the native OCuLink at PCIe x4, this box has more ways to bring in a discrete GPU than anything else we tested.
Storage is the other headline. Three M.2 2280 slots, each supporting up to 8TB, means 24TB of total capacity in a machine this size. Owners running game libraries, media servers or a large Steam collection will not hit that ceiling, but nobody else in this roundup offers three slots.
The processor is a Ryzen 7 H 255, 8 cores and 16 threads up to 4.9GHz on TSMC 4nm Zen 4 with AVX512, driving Radeon 780M graphics with 12 compute units at 2600MHz. Memory is 32GB of dual-channel DDR5-5600 expandable to 96GB, and a fully realized Radeon 780M here handles AV1, AVC and HEVC encode-decode, which makes it a decent streaming box as well as a gaming one. Output reaches quad displays at 8K resolution through HDMI 2.1, DisplayPort 1.4 and USB-C.
There are 13 RGB lighting modes, dual fans published at 35dB in Quiet mode, and a 1-year warranty. Owners also report stable performance with no crashes after the BIOS and microcode updates, which matters more than it sounds for a firmware-heavy box like this.
Who The K12 Fits Best?
The eGPU builder. Several owners pair this with an external GPU over OCuLink for 1080p 60fps gaming, and the storage triple makes it the natural choice for a living-room console that also holds a serious game library. WiFi 6E and dual 2.5GbE LAN complete a machine that can serve as both media box and workstation.
Where The K12 Falls Short?
Buy it knowing that the Ryzen 7 H 255 is a China-market part with limited official documentation. Support exists, it is just not as well trodden as a mainstream SKU, and forum knowledge on this specific chip is thinner than on the 7940HS.
The firmware caveats are real too. There is no S3 sleep state, only modern standby, and the TPM can fail or lock up on resume from that state, which means a reboot. Treat that as an annoyance rather than a dealbreaker, but do not deploy this as an always-on machine that has to survive unattended wake cycles.
5. ACEMAGICIAN S3A – The Quietest Desk In The Roundup
- Ryzen 7 H 255 with Radeon 780M RDNA 3 at 2600MHz and AVX512
- 16GB LPDDR5 at 6400MT/s outpaces the DDR5-5600 kits in most rivals
- Three performance modes with Silent mode published at 35dB
- Tool-free removable 512GB PCIe 4.0 SSD expandable to 4TB
- 2-year warranty plus lifetime technical support
- 16GB of LPDDR5 is soldered and cannot be upgraded
- 512GB of storage fills quickly with modern titles
- Radeon 780M caps serious gaming at 1080p with adjusted settings
Ryzen 7 H 255 to 4.9GHz
Radeon 780M RDNA 3 at 2600MHz
16GB LPDDR5 at 6400MT/s
Silent mode at 35dB with RGB
Fan noise is the number-one complaint in every small form factor community we checked, and the S3A is the machine that answers it most directly. It publishes a Silent mode at 35dB alongside three selectable performance modes, and that kind of published figure is rare in this category.
Under the hood it is a Ryzen 7 H 255 with 8 cores and 16 threads up to 4.9GHz, driving Radeon 780M RDNA 3 graphics at 2600MHz. The memory is the standout spec: 16GB of LPDDR5 at 6400MT/s is faster than the DDR5-5600 kits that most competitors pair with the same chip, and that extra bandwidth shows up directly in integrated-graphics frame rates.
Cooling is dual-fan, with customisable RGB lighting and power profiles ranging from 20W to 54W. Ports are generous for the size, with seven USB ports, WiFi 6E, Bluetooth 5.2, and triple 4K output over HDMI 2.0, DisplayPort 2.0 and USB4 Type-C. Storage is a 512GB PCIe 4.0 drive in a tool-free removable design, expandable to 4TB, which is the most user-friendly drive arrangement in the roundup.
It also carries a 2-year warranty with lifetime technical support, both longer than the 1-year norm, and it runs at 54W in its top mode, so the electrical footprint is small either way.
Who The S3A Fits Best?
Shared rooms, home offices and bedroom setups where a spinning fan is a dealbreaker. If your gaming is evening sessions on a couch rather than a full day of competitive shooters, the Silent mode is the feature that decides it, and the 6400MT/s memory keeps frame rates respectable when you do turn it up.
The tool-free drive is a genuine bonus if you keep swapping SSDs between machines, and the RGB means it does not look like office equipment bolted to the back of a monitor.
Where The S3A Falls Short?
The 16GB of LPDDR5 is soldered. You cannot add memory, and for a machine with this much fast memory, 16GB feels stingy for anything beyond gaming. That is the one decision here you cannot undo.
Its 4.6 average comes from a small sample of 181 reviews, so treat it as encouraging rather than proven. And 512GB fills quickly with modern titles, so budget for a second drive early.
6. Beelink SER9 – Fastest Memory Here And USB4 Charging
- Ryzen AI 7 H350 with 8 cores and 16 threads at up to 5.0GHz
- 32GB LPDDR5X at 7500MHz is among the fastest memory in this roundup
- 1TB PCIe 4.0 x4 NVMe with a second M.2 slot for up to 4TB more
- USB4 40Gbps with power delivery plus dual 3.5mm jacks
- Boots and shuts down in under five seconds and runs very quietly
- 3-year warranty with Windows 11 Pro included
- 32GB of LPDDR5X is soldered and not upgradeable
- Radeon 860M is entry-level for graphics-heavy work
- Some units shipped with a modified Windows 11 install that blocks software installation
Ryzen AI 7 H350 8C/16T to 5.0GHz
Radeon 860M at 3000MHz
32GB LPDDR5X at 7500MHz
USB4 with power delivery
The SER9 is the one to look at if your PC does more than play games. The Ryzen AI 7 H350 gives 8 cores and 16 threads at up to 5.0GHz, which handles office work, editing and light virtualization without complaint, and 32GB of LPDDR5X at 7500MHz is the fastest memory in the roundup.
That memory speed is not just a number. Integrated graphics draw heavily from system bandwidth, so 7500MT/s LPDDR5X gives the Radeon 860M more to work with than the 5600 kits most rivals use. Storage is 1TB of PCIe 4.0 x4 NVMe with a second M.2 2280 slot for up to 4TB more, which is a useful safety net when the memory is fixed.
Ports are where this machine quietly wins. USB4 at 40Gbps with power delivery, plus HDMI, DisplayPort 1.4, 2.5G LAN, four USB ports, a USB-C 10Gbps port and dual 3.5mm audio jacks. Owners praise how fast it boots and shuts down, in under five seconds, and how quiet it is in normal use. The warranty is 3 years with Windows 11 Pro preinstalled.
Be aware that the listed dimensions are not tiny in the way the K1 or the Pinova P2 are, and at 1.43 kg it is a substantial object to move between rooms.
Who The SER9 Fits Best?
Hybrid workstation setups, where the same machine handles a workday of documents, code and light editing, then games in the evening. The port selection means you can connect a proper desktop setup and a laptop-style one without adapters, and USB4 power delivery lets a single cable handle data and charging.
Emulation is the other strong suit here, since 32GB of fast memory and fast storage give emulators the headroom that 16GB machines run out of.
Where The SER9 Falls Short?
The Radeon 860M with 8 cores at 3000MHz is entry-level, suited to emulators and lighter titles rather than anything demanding. If gaming is the main event, spend the money on the P3 Pro or the K11 instead.
Two support issues come up repeatedly. Some units shipped with a modified Windows 11 install that blocks software installation, and driver downloads and documentation are described as vague and hard to navigate. There are also reports of missing internal speakers despite the listing, plus a minority of overheating and early fan failures. Check the warranty terms carefully before buying.
7. ACEMAGIC K1 – The Esports Workhorse With 24GB Already Inside
- Ryzen 7 7735HS gives roughly 35% more CPU and 38% more GPU performance than the 7730U class
- 24GB of LPDDR5 at 5500MT/s handles heavy multitasking and light virtualization
- Two M.2 2280 slots expand storage well past the included 512GB drive
- Compact 5 x 5 inch chassis with an included VESA bracket
- Windows 11 Pro preinstalled with a 2-year manufacturer warranty
- Radeon 680M suits esports and casual titles rather than modern AAA gaming
- 24GB of LPDDR5 is soldered and not user-upgradable
- Inconsistent CPU model metadata across listing variants
Ryzen 7 7735HS 8C/16T to 4.75GHz
Radeon 680M at 2200MHz
24GB LPDDR5 at 5500MT/s
Two M.2 2280 slots
The K1 ranks near the top in the Mini Computers category and carries 2066 reviews, which makes it one of the best-documented machines in this entire category. That matters more than it might sound, because in a segment this young, a large owner base is how we find out about the real failure modes.
The Ryzen 7 7735HS gives 8 cores and 16 threads at up to 4.75GHz with Radeon 680M graphics at 2200MHz. Against the older 7730U, 7430U and 7530U chips, owners measure roughly 35 percent more CPU performance and 38 percent more GPU performance. For competitive shooters, that gap is the difference between holding a stable frame rate and not.
What makes it interesting is the memory. 24GB of LPDDR5 at 5500MT/s is more than most competitors ship, and it is enough for gaming alongside a browser with twenty tabs, Discord and a game launcher, which is the actual usage pattern of a gaming PC. Storage is 512GB with two M.2 2280 slots that expand to 4TB.
Output covers three 4K displays through HDMI, DisplayPort and USB-C, and the chassis measures 5.19 by 5.19 by 1.96 inches, roughly one litre of listed volume, with a VESA bracket included in the box. Power draw is 45W and the warranty is 2 years.
Who The K1 Fits Best?
Anyone whose gaming is Valorant, Counter-Strike, Fortnite, Minecraft or a similar library. At 45W with 24GB of memory and a mount in the box, it is also an easy second machine for a partner who is not a gamer but needs a full desktop, or a home office that games on weekends.
The VESA bracket matters more than it sounds. Mounting the machine behind a monitor or under a desk removes the footprint problem entirely.
Where The K1 Falls Short?
The Radeon 680M is the limit. It handles esports and light titles, and it is not a modern AAA card in any sense. If your library leans toward recent big-budget games, look at the K11 or the P3 Pro, both of which carry faster Radeon 780M graphics.
Two smaller issues. The 24GB of LPDDR5 is soldered, so you are locked in at 24GB permanently. And there is a genuine complaint thread about inconsistent CPU model metadata across listing variants, so confirm which chip you are actually receiving before you compare it to another machine on paper.
8. MINISFORUM AI X1 Pro-370 – The Upgradeable One With A Built-In Power Supply
- Ryzen AI 9 HX370 with 12 cores
- 24 threads at up to 5.1GHz and Radeon 890M graphics
- 32GB of removable DDR5-5600 expands to 128GB unlike soldered rivals
- Three PCIe 4.0 SSD slots reach 7000MB/s and up to 12TB
- Holds around 71C SoC and 81C CPU at full CPU and GPU load
- Built-in 135W power supply removes the external brick and cuts noise
- OCuLink requires an optional M.2 adapter card that occupies a storage slot
- Documentation and support pages are weak with 404s and undocumented drivers
- At 2.45 kg it is the heaviest machine in this roundup
Ryzen AI 9 HX370 12C/24T to 5.1GHz
Radeon 890M
Removable 32GB DDR5
Three PCIe 4.0 slots, built-in 135W PSU
This is the most genuinely expandable machine in the roundup, and for a specific reason: the memory is removable. 32GB of DDR5-5600 sits in sockets and expands to 128GB, which no other machine in this list except the P3 Pro can promise.
The processor is a Ryzen AI 9 HX370 with 12 cores and 24 threads at up to 5.1GHz and Radeon 890M graphics, the same GPU as the far more expensive GEEKOM. Storage is where the design gets serious: three PCIe 4.0 SSD slots, up to 7000MB/s combined, expandable to 12TB. Owners running Linux and virtualization hosts use it exactly this way.
Thermals are genuinely good. Owners report it holding around 71C on the SoC and 81C on the CPU at full CPU and GPU load, with independent CPU and SSD fans published at 45dB. The built-in 135W power supply is an underrated feature: no external brick means no extra heat in the room, one less cable, and less fan noise from a small power supply struggling to stay quiet.
Ports are the most complete in the roundup, with 10 USB ports, two USB4, HDMI 2.1, DisplayPort 2.0, 2.5Gbps LAN, WiFi 7, Bluetooth 5.4, dual DMIC microphones, speakers and a fingerprint sensor.
Who The AI X1 Pro-370 Fits Best?
Anyone who will outgrow 32GB. Whether that is a virtual machine lab, a media server, or a gaming PC that will double as a work machine next year, removable SO-DIMM memory is the feature that keeps this box relevant longest. It also suits anyone who wants a 12-core machine with Radeon 890M graphics without paying the premium tier price.
The fingerprint sensor and built-in PSU make it tidy for a living room or a bedroom desk.
Where The AI X1 Pro-370 Falls Short?
The 4.2 rating is the lowest average in this roundup, and the 10 percent one-star share points at software rather than hardware. MINISFORUM’s documentation and support site draw repeated criticism, with 404 pages and undocumented driver installs, and some units have shipped with a fan that becomes noisy after a few days.
OCuLink is not native here. It needs an optional M.2 adapter card, which occupies one of the three storage slots you are paying to have. There are also reports of poor Bluetooth reception with the stock wireless card, and the BIOS lacks legacy boot support with no clear upgrade path.
9. KAMRUI Pinova P2 – Triple 4K Output For The Least Money
- Ryzen 7330U Zen 3 is about 50% faster single-core and 46% faster multi-core than the Ryzen 3 4300U
- Triple simultaneous 4K60 output across HDMI 2.0
- DisplayPort 1.4 and USB-C
- Quiet fan with an included VESA mount and a light 573 g chassis
- Two M.2 slots expand storage to 4TB
- 2-year warranty with lifetime technical support
- 256GB of onboard storage is small and needs an added SSD for a game library
- Radeon graphics with 6 compute units suit light and older titles only
- 16GB of LPDDR4 is soldered and not upgradeable
Ryzen 7330U 4C/8T to 4.3GHz
16GB LPDDR4 and 256GB SSD
Triple 4K60 via HDMI, DP and USB-C
28W draw with VESA mount
The Pinova P2 is not a gaming PC, and owners are upfront about that. It is a productivity-first mini PC that happens to play games, and at 2040 reviews with a 4.4 average, it is also the most proven machine on this list.
The Ryzen 7330U is a Zen 3 chip with 4 cores and 8 threads up to 4.3GHz on a 15W TDP. Owners measure it as roughly 50 percent faster single-core and 46 percent faster multi-core than the Ryzen 3 4300U, and the 8MB L3 cache outclasses comparable Intel N95 and i3-10110U parts. At 28W and 573 g, it is the lightest and most efficient machine here.
What it does exceptionally well is output. Three simultaneous 4K60 displays through HDMI 2.0, DisplayPort 1.4 and a USB-C with DisplayPort Alt Mode is a rare spec at this end of the market, and it makes the box genuinely useful as a triple-screen productivity machine. Storage is 256GB with two M.2 slots that expand to 4TB, and networking is Gigabit LAN with dual-band WiFi and Bluetooth.
Its fan is quiet, and the VESA mount is in the box. At 5.04 by 5.04 by 1.63 inches, this is the smallest listed footprint in the roundup.
Who The Pinova P2 Fits Best?
Indie gaming, emulation, retro and older titles, plus anyone who wants a genuinely tiny triple-4K productivity machine. It is an excellent HTPC-style box for a living room TV, and at 28W it costs almost nothing to leave running as a home server or download box.
It also makes sense as a travel companion. 573 g, under 2 inches tall and VESA-mountable.
Where The Pinova P2 Falls Short?
The Radeon graphics have 6 compute units at up to 1.8GHz. That is light and older titles, and 3D-heavy modern games are not happening. Set your expectations from the category name rather than the listing photos.
256GB of storage is the other practical limit, and it is small for a game library, so plan to add an SSD immediately. The 16GB of LPDDR4 is soldered and cannot be upgraded.
10. KAMRUI E3B – A 28W Homelab Node With 1TB Of Storage
- Ryzen 7 7730U gives 8 cores and 16 threads
- about 35% more performance than the Ryzen 5 7640HS and 7430U families
- 1TB of storage is generous beside 256GB rivals at similar prices
- Two M.2 slots bring total capacity to 4TB with SATA and NVMe support
- 28W draw suits a home server or firewall role with Wake-on-LAN and Auto Power On
- Radeon graphics with 8 cores at 2000MHz suit mainly casual and older titles
- 16GB of LPDDR4X is soldered and not upgradeable
- Zen 3 architecture lacks AVX512 and trails newer Ryzen 7 7840HS-class chips
Ryzen 7 7730U 8C/16T to 4.5GHz
16GB LPDDR4X and 1TB SSD
Two M.2 slots to 4TB
28W draw with VESA mount
The E3B is the odd one out in this roundup, and that is exactly why it is here. At 28W with 8 cores and 16 threads, it is a general-purpose small server node that happens to run games, not a gaming PC.
The Ryzen 7 7730U delivers 8 cores and 16 threads from 2.0GHz up to 4.5GHz turbo on Zen 3+, with a 16MB L3 cache. Owners measure it as roughly 35 percent faster than the Ryzen 5 7640HS and 7430U families, and the BIOS includes a quiet mode that lets you park the clocks down to 2.0GHz when the machine is doing background work.
Storage is the reason to like it. 1TB as standard, with two M.2 slots taking total capacity to 4TB and support for both SATA and NVMe drives. Combined with 28W power draw, Wake-on-LAN and Auto Power On, that is a complete package for a home server, a NAS-adjacent box, a firewall or a Proxmox node. Output is triple 4K60 through HDMI 2.0, DisplayPort 1.4 and USB-C, and networking is 1000Mbps LAN with WiFi 6 and Bluetooth 5.2 across six USB ports.
No operating system is included, which is exactly what a homelab buyer wants. For a gaming buyer, it is a problem.
Who The E3B Fits Best?
Homelab operators, people running a small always-on machine, and anyone who wants a cheap second desktop for browsing, media and light work. 1TB of storage out of the box removes the most common early upgrade, and the 28W draw means it can sit in a cupboard.
It is also a fine living-room box for older titles and a retro setup.
Where The E3B Falls Short?
The 4.1 rating with a 13 percent one-star share is the second-lowest here, and the reviews suggest a wider spread of unit-to-unit experience than the GMKtec and GEEKOM machines. The Radeon graphics with 8 cores at 2000MHz are for casual and older titles, and the Zen 3 design lacks AVX512 and trails newer Ryzen 7 7840HS-class silicon.
No operating system in the box, and soldered 16GB of LPDDR4X on top of that. If you are buying to game, pick one of the first eight machines instead.
SFF Gaming PC Buying Guide: What Actually Matters?
Before buying any of the above, work out which tier of small form factor you are actually shopping for. The tiers differ more in what they can be upgraded to than in their size.
The smallest tier is the NUC-style and micro desktop box, generally under 1 litre of listed volume. Machines like the ACEMAGIC K1 and the KAMRUI Pinova P2 sit here, and they are fan-cooled, wall-mountable and cheap. They are excellent as a second machine, an HTPC or a productivity box, and they are not trying to be 3D gaming machines.
The middle tier is the sub-3 litre gaming mini PC, and this is where most of the interest in the best small form factor gaming PCs sits. These are boxes with socketed or fast soldered memory, multiple M.2 slots and Radeon 780M or 890M graphics. The K11, K12, P3 Pro, S3A, SER9 and AI X1 Pro-370 are all in this group.
The top tier is true Mini-ITX: a standard 170 by 170mm motherboard, a full-length PCIe x16 slot and a desktop graphics card, in a case typically between 10 and 20 litres. This is where desktop-class gaming performance genuinely lives, and where the form factor stops being a constraint and starts being a hobby. We have covered the parts side of that in our small form factor PC guide and our gaming PC roundups.
Integrated Graphics Are The Honest Limit
Every machine in this roundup uses integrated Radeon graphics, and that single fact sets your ceiling. The Radeon 890M and 780M chips are the strongest of the group, and they are capable of 1080p gaming with settings adjusted. They are not capable of what a discrete card does, and the marketing does not always make that clear.
There is one honest escape route, and it is OCuLink. An external GPU over OCuLink at PCIe x4 runs close to desktop-class performance at 1080p, and several owners in our research do exactly this. The catch is that an external GPU enclosure plus a graphics card costs more than a used tower, which defeats the purpose of a compact system in the first place.
Check Memory Before Anything Else
Soldered memory is the decision you cannot reverse. Machines with LPDDR5 or LPDDR5X soldered are stuck at whatever shipped, and in this roundup that ranges from 16GB of LPDDR5 on the S3A to 24GB on the K1, with the SER9 fixed at 32GB of very fast but non-replaceable LPDDR5X. If you want headroom in three years, buy socketed memory: the K11, the P3 Pro and the AI X1 Pro-370 all take removable DDR5.
Storage is the easier upgrade, since most of these have two M.2 slots at minimum. The K12 has three. Check whether the second slot is SATA or NVMe, and whether reaching it requires opening the case.
Noise, Thermals And Why Published dB Matters
Small form factor fan noise is the most common complaint in every community we checked, and it is the one spec most spec sheets hide. When a manufacturer publishes a figure, take it. Four machines here do: the K11 and K12 at 35dB in Quiet mode, the S3A at 35dB in Silent mode, and the AI X1 Pro-370 at 45dB under full load.
The pattern most buyers report is consistent. Fanless designs are wonderful for office work and throttle quickly in games. Active cooling means noise. The question is whether the manufacturer lets you choose, and a machine with selectable performance modes lets you keep it quiet for desktop work and let it spin up only when a game is running.
Coil whine is a separate problem from fan noise, and it is harder to predict. Owners across this category report it on several brands, and the usual pattern is that a coil-whine return is difficult to get resolved. Treat it as an accepted risk rather than something you can shop your way out of.
SFF Desktop Or Gaming Laptop?
This is the single most common question in small form factor communities, so let us answer it directly. If you have not already worked through our small gaming PC roundup, start there. A gaming laptop gives you a screen, a keyboard, a battery and one cable to a desk. A small form factor PC gives you a desktop you can mount behind a monitor or a TV, far more upgrade flexibility, and usually a better price per unit of performance.
If you game in one place, a small form factor PC wins on cost and upgradability. If you game in several places, the laptop wins on convenience, and no mini PC makes that trade for you. The forum consensus we found is that for a second rig in an apartment, the mini PC is the better answer as long as there is somewhere to put it.
One more factor for anyone building a second machine: Windows bloatware on office-refurbished micro desktops needs a clean install, and BIOS fan curve control on OEM units is often locked down. Buying new in this roundup avoids both problems.
Frequently Asked Questions
Are small form factor PCs good for gaming?
Yes, for 1080p gaming. The best small form factor gaming PCs use laptop-class processors with Radeon 780M, 860M, 890M or 680M integrated graphics, which handle esports titles at high refresh rates and lighter AAA games with settings adjusted. They are not a substitute for a discrete desktop GPU at 1440p or 4K.
What is the best value small form factor PC?
The BOSGAME P3 Pro is our value pick. It pairs a Ryzen 9 7940HS with 16GB of DDR5-5600 that you can upgrade to 64GB, which is unusual at this price since most rivals ship soldered memory. Add an operating system and a second SSD and it covers most of what people want from a compact gaming PC.
What is the smallest form factor for a PC?
The smallest desktop form factors are NUC-style and micro desktops, generally under 1 litre of listed chassis volume and often around 0.5 to 1 litre. The ACEMAGIC K1 at 5.19 by 5.19 by 1.96 inches and the KAMRUI Pinova P2 at 5.04 by 5.04 by 1.63 inches are examples. Handhelds and stick PCs go smaller still, but with no gaming upgrade path.
Which mini PC brand is best for gaming?
GEEKOM, GMKtec and BOSGAME are the strongest choices in this roundup on warranty length, memory speed and upgradeability. GMKtec leads on connectivity with native OCuLink and dual 2.5GbE LAN, GEEKOM offers the longest warranty at 3 years, and BOSGAME gives the most memory per unit of money. Brand reliability matters less than checking whether your specific model has soldered memory.
Are mini PCs actually good for gaming?
They are good for 1080p gaming and excellent for everything else a small PC does. Integrated Radeon graphics in current Ryzen AI and Ryzen 7000H chips are several times faster than the older integrated graphics mini PCs shipped with, and the gap keeps narrowing each generation. Where mini PCs still fall short is high-refresh 1440p and ray tracing, which need a discrete GPU.
How loud are mini gaming PCs?
It varies widely, and this is the most commonly reported complaint. Machines in this roundup that publish a figure list 35dB in Quiet or Silent mode for the GMKtec K11, GMKtec K12 and ACEMAGICIAN S3A, and 45dB under full load for the MINISFORUM AI X1 Pro-370. Fanless models are silent but throttle in games, so look for selectable performance modes.
Can you upgrade a mini gaming PC?
Partly. Storage is usually upgradeable, with two M.2 slots common and three on the GMKtec K12. Memory is the real question: the GMKtec K11 and MINISFORUM AI X1 Pro-370 use removable DDR5, while the ACEMAGIC K1, ACEMAGICIAN S3A, Beelink SER9 and both KAMRUI machines ship soldered LPDDR memory that cannot be replaced.
Is a mini PC better than a gaming laptop?
A small form factor PC is better for gaming in one fixed location because it costs less per unit of performance, runs cooler and quietly, and can be mounted behind a monitor or a TV. A gaming laptop is better if you play in several places, since it includes a screen and battery. For a second rig in a small apartment, a mini PC is usually the stronger answer as long as it has a home.
Final Verdict: Which Small Form Factor Gaming PC To Buy?
The GMKtec K11 is the best small form factor gaming PC in 2026, and the reason is headroom rather than raw speed. Eight Zen 4 cores, 32GB of fast dual-channel DDR5, dual Gen4 storage slots, a native OCuLink port and two 2.5GbE NICs in one box leaves you somewhere to go, whether that is an external GPU, a virtualisation host or just a game library that outgrows 512GB.
Buy the BOSGAME P3 Pro if upgradable memory matters most to you and you want Zen 4 performance for as little as possible. Buy the GEEKOM A9 Max if you want the strongest integrated graphics available and the memory to run real VMs alongside gaming, and only if the price difference is easy for you to absorb.
For a quiet desk, the ACEMAGICIAN S3A is the answer, with a published silent mode and 6400MT/s memory. For a gaming PC that doubles as a home server, the MINISFORUM AI X1 Pro-370 wins on removable RAM, three SSD slots and a built-in power supply. And for esports, a second machine in a shared flat, or anything that needs to mount behind a screen, the ACEMAGIC K1 remains the best-proven machine in the category with 24GB of memory and a VESA bracket in the box.
Whatever you choose, buy the one with socketed memory if you can, and check the noise figure before you check anything else.
