4. Which small form factor PC should you choose?

The best small form factor PC for most people is the GMKtec M6 Ultra, with 32GB of DDR5 memory, a Ryzen 5 7640HS and three display outputs. If you need a lower-cost everyday desktop, compare the KAMRUI AK1PLUS and Beelink SER3; for more storage and three displays, consider the GMKtec G10.

Small form factor PC can mean different things. Some shoppers want a tiny computer that mounts behind a monitor, while others mean a compact desktop that leaves more room for drives, memory or ports.

These picks are mini PCs, so compare the listed upgrade options and connections rather than assuming they offer tower-like internal space. Our step-by-step guide to choosing a mini PC explains how to weigh size, workload and connections.

How we chose these small form factor PCs

We compared processor, memory, included storage, display support, ports and stated upgrade options against common compact-desktop needs. Our score weighs specs, features and buyer feedback against what you're shopping for.

This list spans basic home computing, multi-monitor work, extra storage and heavier multitasking. The highest score is not a promise that a PC fits every desk or workload, so use the individual strengths and tradeoffs to narrow your choices.

A small label alone does not tell you how much room a system gives for expansion. Check whether memory is replaceable, how many storage slots are available, and which monitor connections you can use at the same time.

Which small form factor PC fits your work?

The right small form factor PC depends on how much processing power, storage and display support you need. These picks are ordered by score, with each one suited to a different setup.

9.7/10Our score

• Intel Celeron N5095
• 16GB LPDDR4X memory
• 256GB SSD
• Supports 2.5-inch drive expansion

The AK1PLUS pairs a modest processor with 16GB memory and support for additional M.2 and 2.5-inch storage. Its dual HDMI outputs support two 4K displays.

See it on Amazon

Pros

• Two HDMI 2.0 outputs
• Supports an added 2.5-inch drive
• Four USB 3.2 ports

Cons

• Celeron processor is aimed at everyday computing
• Wi-Fi is 802.11ac

The KAMRUI AK1PLUS is aimed at everyday computing such as web browsing, online classes, video calls and email. Its Intel Celeron N5095 pairs with 16GB of LPDDR4X memory and a 256GB SSD.

The key flexibility is storage: it supports an M.2 SATA or NVMe drive and an additional 2.5-inch SATA SSD or hard drive. The brand describes support for up to 4TB total across those drives, with upgrades sold separately.

Two HDMI 2.0 ports support two 4K displays at up to 60Hz. Four USB 3.2 ports, Gigabit Ethernet and a 3.5mm audio jack cover common desk connections.

Choose it for a compact home or office setup with room to add storage. If you expect demanding creative work or heavy multitasking, compare its processor with the Ryzen options below.

2

Beelink SER3 Mini PC: Best for a roomy starting SSD

9.7/10Our score

• AMD Ryzen 3 3200U
• 16GB DDR4 memory
• 500GB M.2 SSD
• Supports up to 32GB memory

The SER3 comes with a 500GB SSD and 16GB of memory, with a stated memory upgrade path to 32GB. Dual HDMI outputs support a two-screen setup.

See it on Amazon

Pros

• 500GB SSD included
• Memory can expand to 32GB
• Dual HDMI outputs

Cons

• Two-core, four-thread processor
• Uses Wi-Fi 5

The Beelink SER3 gives you a 500GB M.2 SSD and 16GB of DDR4 memory from the start. Its Ryzen 3 3200U is a two-core, four-thread processor, and memory can be expanded to 32GB.

Dual HDMI outputs support a two-screen desk. The PC also has four USB 3.2 ports, Gigabit Ethernet, dual-band Wi-Fi 5 and Bluetooth.

This is a reasonable fit for office work, online courses, media playback and light multitasking. The processor is less suited to sustained heavy workloads than the newer, higher-tier processors in this roundup.

Choose it if the included storage matters more than having the highest processor performance. Linux users can compare the hardware considerations in our guide to the best mini PC for Linux.

GMKtec G10 Mini PC Ryzen 5 3500U: Best for three displays and drive expansion

9.6/10Our score

• AMD Ryzen 5 3500U
• 16GB DDR4 memory
• 1TB SSD
• Three display outputs

The G10 combines a 1TB SSD with two M.2 slots and three display connections. Its 2.5GbE port may also suit a wired network that supports that speed.

See it on Amazon

Pros

• 1TB SSD included
• Three simultaneous display connections
• 2.5GbE Ethernet

Cons

• Wi-Fi 5 rather than Wi-Fi 6
• RAM and storage upgrades are not included

The GMKtec G10 combines an AMD Ryzen 5 3500U with 16GB of DDR4 memory and a 1TB SSD. Two M.2 2280 slots give it a clear path to add storage, and GMKtec says the memory can expand to 64GB.

Its HDMI, DisplayPort and full-function USB-C connections support three simultaneous displays. The USB-C port handles display, data and power delivery, while the 2.5GbE Ethernet port supports faster wired networking when the rest of your network does too.

That mix suits a desk with several screens, a larger local file library or a wired server role. The graphics are integrated Radeon Vega 8, so this is better framed as a casual gaming and productivity system than a dedicated gaming desktop.

Pick the G10 if its storage and three-display support matter more than newer wireless standards. If fast external connections are a priority, see our best mini PCs with Thunderbolt 4 guide and compare its ports with those systems.

4

GMKtec M6 Ultra Gaming Mini PC Ryzen: Best for demanding multitasking

9.5/10Our score

• AMD Ryzen 5 7640HS
• 32GB DDR5 memory
• 1TB PCIe SSD
• Dual 2.5GbE Ethernet

The M6 Ultra has the strongest stated processor and memory combination in this group. USB4, HDMI and DisplayPort provide three display connections.

See it on Amazon

Pros

• Six-core, 12-thread processor
• 32GB DDR5 memory
• Three display outputs

Cons

• Its performance-focused hardware may be more than basic office work needs
• Storage upgrades are not included

The GMKtec M6 Ultra is the strongest pick here for demanding multitasking. It pairs a six-core, 12-thread Ryzen 5 7640HS with 32GB of DDR5 memory and a 1TB M.2 SSD.

Its three display connections include USB4, HDMI 2.0 and DisplayPort. GMKtec lists support for three simultaneous displays, including up to 8K at 60Hz through USB4 and 4K at 60Hz through HDMI and DisplayPort.

Two 2.5GbE Ethernet ports add flexibility for a wired workstation or server. The Radeon 760M integrated graphics and stated support for moderate gaming make it more capable than an entry-level office PC, though it still isn't a system with a separate graphics card.

Choose the M6 Ultra if you need its higher processor and memory configuration, multiple displays or dual wired networking. For web, email and documents, one of the less powerful choices may be a better fit.

5

HP Pro 400 G9 Mini PC Desktop: Best for a Windows 11 Pro setup

9.0/10Our score

• Intel Core i3-13100T
• 16GB DDR5 memory
• 256GB PCIe SSD
• Windows 11 Pro

The HP includes Windows 11 Pro, a keyboard and a mouse, which can simplify a new desktop setup. Its two DisplayPort outputs and HDMI support multiple screens.

See it on Amazon

Pros

• Windows 11 Pro included
• Keyboard and mouse included
• USB-C and multiple display outputs

Cons

• 256GB SSD is the smallest stated storage here
• The dimensions appear inconsistent, so confirm the chassis size

The HP Pro 400 G9 suits buyers who want a Windows 11 Pro desktop with basic accessories included. Its Intel Core i3-13100T is paired with 16GB of DDR5 memory and a 256GB PCIe SSD.

The connection list includes USB-C, USB-A, Ethernet, HDMI and two DisplayPort outputs. A keyboard and mouse are included, which can help you get a desk running without shopping for those separately.

HP describes the chassis as weighing less than 3 lb. Its dimensions appear inconsistent with the compact size claim, so confirm the exact measurements with the seller before planning a tight installation.

Pick this model for the included Windows 11 Pro setup and familiar HP desktop format. If compact physical size is the deciding factor, verify that the chassis will fit your planned space.

BOSGAME P4 Ultra Mini PC: Best for dual wired networking

9.0/10Our score

• AMD Ryzen 7 7730U
• 16GB DDR4 memory
• 1TB PCIe SSD
• Dual 2.5GbE ports

The P4 Ultra combines a Ryzen 7 processor with two 2.5GbE ports and three display outputs. It can suit a home office or server setup that benefits from wired network connections.

See it on Amazon

Pros

• Dual 2.5GbE Ethernet ports
• 1TB SSD and second M.2 slot
• Three display outputs

Cons

• 16GB memory is less than the M6 Ultra's 32GB
• Wi-Fi 6E benefits depend on your network

The BOSGAME P4 Ultra is a fit for dual wired networking and three-screen work. Its Ryzen 7 7730U has eight cores and 16 threads, alongside 16GB of dual-channel DDR4 memory and a 1TB PCIe SSD.

Two 2.5GbE ports can serve a home server or workstation that uses multiple wired network connections. HDMI, DisplayPort and USB-C provide three display outputs, and the system supports adding a second M.2 drive.

The stated memory upgrade ceiling is 64GB. Wi-Fi 6E and Bluetooth 5.2 are also listed, but you'll need compatible network gear and peripherals to use those features.

Choose the P4 Ultra for its dual Ethernet ports and storage capacity. The M6 Ultra starts with more memory and a newer processor, while the P4 Ultra offers its own useful wired-network layout.

7

KAMRUI Pinova P2 AMD Ryzen 5425U: Best for compact triple-display setups

8.9/10Our score

• AMD Ryzen 5 5425U
• 16GB LPDDR4 memory
• 256GB SSD
• Three 4K display outputs

The Pinova P2 offers HDMI, DisplayPort and USB-C display connections in a small chassis. Its two M.2 slots allow additional storage, while memory is listed as 16GB LPDDR4.

See it on Amazon

Pros

• Three display outputs
• Two M.2 storage slots
• Six USB-A ports

Cons

• 256GB SSD included
• Check the exact memory upgrade options before buying

The KAMRUI Pinova P2 fits a small desk that needs three displays. Its 5.05 x 5.05 x 1.73 in dimensions and VESA mount option can help keep the computer out of the way.

It uses an AMD Ryzen 5 5425U, 16GB of LPDDR4 memory and a 256GB SSD. HDMI, DisplayPort and USB-C support three 4K displays at up to 60Hz, while two M.2 slots allow storage expansion.

The port mix also includes six USB-A ports, Gigabit Ethernet and a 3.5mm audio jack. That can reduce the need for a separate hub when your desk has several wired devices.

Choose the Pinova P2 if small physical size and three-screen output matter more than a large starting SSD. Check the exact memory upgrade options before buying, since its memory is LPDDR4.

What should you check before choosing a compact desktop?

Compare physical dimensions, memory, storage and ports before choosing a compact desktop. Those details determine whether it fits your desk and handles the devices and workloads you already have.

Does a small form factor PC have enough expansion space?

Expansion varies by model, so look for specific memory and storage details rather than relying on the small form factor label. The AK1PLUS supports an added 2.5-inch drive, while the G10 and Pinova P2 list two M.2 storage slots.

The SER3 and BOSGAME P4 Ultra also state memory upgrade options. The M6 Ultra pairs its 32GB of DDR5 memory with dual-slot storage expansion, while the HP's product details describe support for higher memory and SSD capacities.

How many displays do you need?

Match each monitor to a port on the computer and check the number of displays supported at once. Dual HDMI makes the AK1PLUS and SER3 straightforward choices for two screens, while several other picks offer three different display connections.

USB-C display support depends on the specific port, cable and monitor. Confirm the connection type and resolution you plan to use before choosing a PC for a multi-monitor desk.

Is a cheap small form factor PC enough?

A cheap small form factor PC can be enough for browsing, documents and video calls if its processor, memory and storage fit those jobs. The AK1PLUS is the most entry-level processor option here, while the SER3 includes a larger SSD and a two-screen connection layout.

For heavier multitasking, compare the Ryzen 5 and Ryzen 7 systems. Choose based on the software you use and the storage or display needs you have, rather than paying for capacity you won't use.

Will it work with your operating system and accessories?

Check the included operating system, wireless support and ports before you buy. The HP comes with Windows 11 Pro, while the other product details here don't specify an operating system in the same way.

If you're comparing Windows options, our guide to the best Windows mini PC covers systems selected for that use. Also check whether you need USB-C, Ethernet, a headset jack or a compact input set; our best compact keyboard and mouse combo guide can help round out a small desk.

Which small form factor PC should you choose?

Choose the GMKtec M6 Ultra if you want the strongest stated processor and memory setup in this group. Pick the HP Pro 400 G9 for Windows 11 Pro and included keyboard and mouse, or the AK1PLUS for basic daily work with a 2.5-inch storage expansion option.

For three displays and a 1TB SSD, compare the GMKtec G10 and BOSGAME P4 Ultra. Choose the Pinova P2 when a particularly small chassis matters, and the Beelink SER3 when a 500GB SSD and two displays fit your needs.

Frequently asked questions

What is a small form factor PC?

A small form factor PC is a desktop built to take up less room than a traditional tower. The term can cover compact mini PCs as well as larger compact desktops, so compare the actual chassis dimensions, ports and upgrade options for the system you want.

A larger enclosure may leave more room for expansion, but check the specific model rather than assuming.

Is a mini PC the same as a small form factor PC?

Mini PCs are one kind of small form factor computer, but the terms aren't always used the same way. Some buyers use small form factor to mean a compact desktop with more room for drives or memory than a tiny mini PC.

Check the dimensions and internal upgrade details before choosing by label alone.

How much memory should a small form factor PC have?

For everyday browsing, office work and video calls, 16GB is a practical starting point among these picks. More memory can help when you keep many apps open or use heavier creative software.

Check whether memory is upgradeable and whether the computer uses replaceable modules or built-in memory.

Can a small form factor PC run multiple monitors?

Yes, several models here support two or three displays, but the connection types and supported resolutions vary. The G10, M6 Ultra, BOSGAME P4 Ultra and Pinova P2 list three display connections.

Match your monitor inputs to the PC's HDMI, DisplayPort or USB-C outputs before you buy.

What should I check before buying a cheap small form factor PC?

Check the processor, memory, SSD capacity, ports and upgrade path before choosing a low-cost compact PC. A lower price can come with a more modest processor or less storage, and those limits matter if you plan to run several apps at once.

Also confirm the operating system and physical dimensions.
