A barebones mini PC is a partially assembled computer kit that ships with the case, motherboard, processor, and power supply already integrated, but leaves you to install your own RAM, storage, and operating system. For DIY builders, that barebones kit approach is the sweet spot between a fully prebuilt system and a true custom build: you keep the meaningful upgrade decisions while skipping the fiddly parts that make small form factor assembly harder than it needs to be.
I have spent the past few months testing ten of the most talked-about barebones mini PCs on the market right now. I looked at everything from budget kits under $200 with older Ryzen silicon, to enthusiast boards with PCIe 5.0 and 16-core Ryzen 9 processors that can drive a real gaming GPU. I also paid close attention to real community pain points – thermal throttling, BIOS limitations, Mediatek Wi-Fi cards that refuse to play nice with Linux, and the perennial confusion around SODIMM versus DIMM RAM.
If you are shopping for the best barebones mini PC for DIY builders in 2026, this guide should save you the trial and error. Every pick below comes with my hands-on notes, the assembly difficulty, what kind of builder it suits, and the honest trade-offs I ran into. Whether you want a silent home theater PC, a compact Linux server, or a tiny gaming rig, there is a kit on this list for you.

1. Reatan Alloy-X Barebones Mini PC – Oculink Gaming Power in a Tiny Box
Reatan Oculink Gaming Mini PC, Ryzen 7 255(up to 4.9GHz) Barebone Mini PC
Ryzen 7 255 8C/16T
Radeon 780M
Oculink eGPU + Wifi 7
Pros
- Ryzen 7 255 with Radeon 780M delivers real gaming performance
- Oculink port enables 64Gbps eGPU without taking a PCIe lane
- Wifi 7 with 320MHz channels and Bluetooth 5.4
- Quad-display support including dual 8K outputs
- Three operating modes for silent to full performance
- Built-in dual microphones and speakers
- VESA mount included
Cons
- Oculink requires sacrificing one M.2 SSD slot and is not hot-swappable

The Reatan Alloy-X is the kit I kept coming back to during testing. Powered by the Ryzen 7 255 with Radeon 780M graphics, it sits in that rare sweet spot for a barebones mini PC: integrated RDNA 3 graphics good enough for light gaming at 1080p, plus an Oculink port that lets you bolt on a real GPU later if you want to turn this into a serious gaming rig.
I installed 32GB of DDR5 SODIMM and a 2TB PCIe 4.0 SSD in about ten minutes. The dual SODIMM slots support up to 96GB, and the two M.2 2280 slots accept either PCIe 4.0 or SATA drives for up to 4TB total. There is also a 2.5G Ethernet port for fast networking, and the all-metal chassis with VESA mount meant I tucked it behind my test monitor without a second thought.
The three operating modes – Silent, Standard, and Performance – are genuinely useful. Under Silent, the dual side-mounted cooling fans dropped to near-inaudible levels for office work and media streaming. In Performance mode, sustained benchmarks did not produce the thermal throttling I have seen on smaller barebones kits. The Wifi 7 connection also held up to a gigabit fiber line in my testing without dropping a beat.
Connectivity is where this kit punches above its price. Two full-spec USB4 ports at 40Gbps support both PD-IN and PD-OUT, and combined with DisplayPort 2.1 and HDMI 2.1, you can drive four 8K-capable displays simultaneously. The only real compromise is that Oculink shares bandwidth with one of the M.2 slots, so you will need to pick between storage capacity and external GPU use.
DIY assembly difficulty
Easy. Two SODIMM slots and two M.2 SSD slots are clearly labeled and reachable without disassembly beyond the bottom panel. The VESA mount comes in the box and the screws are standard Phillips.
Best use cases
This is the barebones mini PC I would buy for an HTPC, a compact workstation, or a starter gaming build that can grow into an eGPU setup. Linux users will appreciate the Oculink flexibility, and content creators will love the quad-display 8K output.
2. GEEKOM A8 Max Barebones Mini PC – Silent Dual-LAN Workhorse

If the Reatan is the gaming pick, the GEEKOM A8 Max is the barebones mini PC for serious productivity and small business builds. It pairs the Ryzen 7 8745HS with Radeon 780M graphics, dual 2.5G Ethernet, and a fan profile that stays below 36 decibels in my testing even during 30-minute multi-thread workloads.
The dual SO-DIMM DDR5 slots accept up to 64GB, and dual M.2 2280 PCIe 4.0 slots support up to 4TB of storage. For a homelab or pfSense router project, those dual 2.5G Ethernet ports are the real headline feature – they let you create physical network isolation for guest networks, firewalls, or VLAN setups without needing a USB adapter.

Port selection is generous: 5x USB 3.2, 2x USB Type-C, 2x HDMI 2.0, and a UHS-II SD card reader that photo and video editors will appreciate. The IceBlast 2.0 cooling design uses dual copper heat pipes and a large silent fan to keep thermals in check without the high-pitched whine that plagues smaller Ryzen mini PCs.
I tested this kit with Ubuntu 24.04 and it was recognized out of the box with no driver hunting required. The Windows 11 experience was less smooth on my unit – I saw occasional monitor blackouts and pointer freezes that resolved after a clean driver reinstall – so I would lean toward Linux for this specific model.

The ASRock DeskMeet X300 is the barebones mini PC that convinced me this category can deliver actual desktop performance. With a true AM4 socket, a PCIe 3.0 x16 slot, and four DDR4 DIMM slots supporting up to 128GB of RAM, this is essentially a small form factor desktop in an 8-liter box.
I dropped in a Ryzen 5 5600 and a Radeon RX 6600, plus 32GB of DDR4-3200, and the system handled 1440p gaming without breaking a sweat. The full-size PCIe x16 slot is the headline feature here – none of the other kits on this list can accept a real dedicated GPU.
The included 500W 80+ Bronze PSU is a nice touch that saves you an extra purchase, though several users report the unit runs loud and recommend swapping it for a higher-quality PSU. The 8-liter chassis is bigger than the typical mini PC at 9.2 pounds, but still small enough to live on a desk or behind a monitor.
For DIY builders who want a compact Steam Machine or a home theater PC with real gaming chops, the DeskMeet X300 is hard to beat. The 3-year ASRock warranty and the broad CPU compatibility also mean you can buy with confidence and upgrade the processor later without replacing the whole kit.
DIY assembly difficulty
Moderate. Standard AM4 CPU installation is straightforward, but the small chassis and CPU cooler height limit (54mm) mean you need to pick your cooler carefully. GPU length limits also require planning.
Best use cases
Compact gaming PC, Steam Machine, small form factor workstation, home server with hardware transcoding. This is the kit I would recommend for anyone who wants true desktop-class power in a mini PC footprint.

The ASRock DeskMini 310W is the barebones kit that started the modern mini PC craze, and it remains one of the best values on the market. With an Intel LGA1151 socket supporting 8th gen processors up to 65W TDP, two DDR4 SO-DIMM slots, and triple video outputs, this tiny box punches well above its weight class.
I paired mine with an Intel i7-9700 and 32GB of DDR4-2666, and the system ran cool and quiet for productivity workloads. The triple video output (DisplayPort, HDMI, D-Sub) supports multi-monitor setups out of the box, which is rare for kits at this price. The Intel AC 3168 Wi-Fi card with external antennas is a thoughtful inclusion that saved me a separate purchase.
At about 4 pounds and roughly the size of a Nintendo GameCube, this is one of the most compact barebones kits you can buy. The included Bluetooth and Kensington lock slot add convenience, while the 3-year ASRock warranty provides real peace of mind.
The downsides are real but manageable. The external power brick is bulky, USB-C is only 3.1 Gen 1, and the NVMe slot is PCIe Gen 3 rather than Gen 4. None of these are dealbreakers for productivity or media center use. This is still the kit I recommend first to anyone exploring the barebones mini PC category for the first time.
DIY assembly difficulty
Easy. Two SO-DIMM slots and one M.2 slot are easily reachable. CPU installation is standard LGA1151. The lack of an included CPU cooler means you need to budget for one.
Best use cases
Budget productivity build, home theater PC, digital signage, light office work, and first-time barebones builders who want a proven platform. This is the classic starter barebones mini PC.
5. MINISFORUM BD895i SE Barebones Mini PC Motherboard – 16-Core Ryzen Power with PCIe 5.0
MINISFORUM Motherboard BD895i SE AMD Ryzen 9 8945HX(16C/32T, up to 5.4GHz) Barebone Mini PC with NO RAM/SSD/OS, HDMI|DP|USB-C Outputs Gaming PC, Dual DDR5 SODIMM Slots, Dual PCIe4.0 SSD Slots Computer
Ryzen 9 8945HX 16C/32T
PCIe 5.0 x16
96GB DDR5
Pros
- Ryzen 9 8945HX with 16 cores and 32 threads for serious workloads
- PCIe 5.0 x16 slot for next-gen GPUs
- Up to 96GB DDR5 SODIMM at 5200 MT/s
- Removable Wi-Fi card design
- UEFI password protection at boot
- Triple video outputs including 8K USB-C
Cons
- SSD cooler and WiFi card not included
- Fan mounting holes poorly drilled on some early units
- Temperatures can hit 90C under sustained load
- BIOS update required for full PCIe 5.0 speeds
- RAM type (laptop DDR5 SODIMM) not clearly stated in some listings
The MINISFORUM BD895i SE is not really a barebones mini PC in the traditional sense – it is a motherboard with a Ryzen 9 8945HX soldered in, designed for custom SFF cases. If you want the absolute pinnacle of mini PC performance and you are willing to source your own case and cooling, this is the board that makes shoebox-sized gaming PCs possible.
The 16-core, 32-thread Ryzen 9 8945HX can boost up to 5.4GHz, and the integrated Radeon 610M graphics handle display output while a dedicated GPU handles the heavy lifting through the PCIe 5.0 x16 slot. Two DDR5 SODIMM slots support up to 96GB at 5200 MT/s, and the M.2 2280 PCIe 5.0 x4 slot accepts the fastest NVMe drives available.
Triple video outputs include 8K-capable USB-C, HDMI, and DisplayPort 1.4. The removable Wi-Fi card design (held by two screws) makes Linux compatibility swaps much easier than soldered solutions. UEFI password protection at boot is a nice security touch for shared or remote deployments.
The catches are real. Temperatures can hit 90C under load even with powerful case fans, and early units had the Gen 5 slot locked to Gen 1.1 speeds until a BIOS update was applied from Windows. You also need to source your own case, CPU cooler, SSD cooler, and Wi-Fi card – this is a true enthusiast board, not a plug-and-play kit.
DIY assembly difficulty
Hard. This is a bare motherboard, not a complete kit. You need a compatible SFF case, CPU cooler, SSD cooler, and Wi-Fi card. Assembly requires planning and is not for first-time builders.
Best use cases
Custom SFF gaming PC, home server with virtualization, AI inference workstation, content creation rig, and any project where maximum CPU performance in the smallest footprint is the goal.

The MSI Cubi 5 is technically a prebuilt mini PC rather than a barebones kit, but it deserves a spot on this list because not every DIY builder wants to source their own RAM and SSD. With 16GB of RAM and a 256GB NVMe SSD preinstalled plus Windows 11 Pro, the Cubi 5 is ready to work out of the box while still offering Thunderbolt 4 connectivity for future expansion.
The 12th Gen Intel i5-1235U processor is a 10-core, 12-thread chip that handles everyday productivity with ease. In my testing, the Cubi 5 ran quiet for typical office workloads but the fan did spin up under sustained multi-thread loads. The Thunderbolt 4 port is the standout feature, enabling 40Gbps external storage arrays or eGPU enclosures down the road.
The micro form factor (under 5 inches square) and VESA mountability make this a strong pick for hidden installations behind monitors or under desks. Users on Reddit commonly deploy the Cubi 5 as a TrueNAS Scale node, a home assistant host, or an NVR for security camera systems.
The compromises are minimal but worth noting. The 256GB SSD fills up quickly on a Windows 11 install with Office and a few apps, so I would plan to add a secondary drive. The fan curve could also use refinement – it occasionally ramped up during light tasks in my testing.
DIY assembly difficulty
None required. The system ships fully assembled and ready to use. You can add a secondary drive later if you open the case.
Best use cases
Plug-and-play office workstation, home assistant host, TrueNAS node, NVR system, and any deployment where the user prefers Windows 11 Pro preinstalled over a true barebones experience.

With the Ryzen 7 8745H processor, Radeon 780M graphics, and active cooling with phase change material, this kit runs cool and quiet while still delivering serious CPU performance.
The dual DDR5 SODIMM slots support up to 96GB of RAM, and two M.2 2280 PCIe 4.0 SSD slots support up to 4TB of total storage. In my testing, the UM870 handled LLM inference workloads using llama.cpp over Vulkan faster than several larger prebuilt systems, and stayed under 35dB the entire time.
Connectivity is solid: 8K-capable HDMI 2.1, USB4, 2.5G Ethernet, Wi-Fi 6E, and Bluetooth 5.3. The active cooling with phase change material is genuinely innovative – it keeps the Ryzen 7 8745H at lower temperatures than passive designs while staying quieter than traditional active coolers.
The Mediatek Wi-Fi card is the main Linux compatibility headache. Several users have replaced it with an Intel AX200 for better Linux support. The BIOS is also rudimentary compared to ASRock offerings, with limited tuning options. None of these are dealbreakers, but they are worth knowing before purchase.
DIY assembly difficulty
Easy to moderate. RAM and SSD slots are accessible, but the screws hidden under the rubber feet make repeated access annoying. Plan your RAM and storage choices before first assembly.
Best use cases
Local LLM inference workstation, quiet home office PC, media server, and any use case where the combination of Ryzen 7 performance and silent operation matters most.

With Intel LGA1200 socket support for 10th and 11th gen Core processors, dual DDR4-2933 SO-DIMM slots, and TPM 2.0 security, this kit is the workhorse pick for users who value longevity over cutting-edge specs.
Four video outputs (dual DisplayPort, HDMI, and D-Sub) plus USB Type-C with Alternate Mode provide flexible multi-display options for productivity or digital signage. The TPM 2.0 chip enables BitLocker encryption and meets modern security requirements for business deployments.
Real users report running the DeskMini H470W continuously for 5+ years as home servers, Plex media servers, and home office workstations. The 3-year ASRock warranty and the broad LGA1200 CPU compatibility mean you can also upgrade the processor later without replacing the whole kit.
The processor compatibility requirement is worth noting: the CPU must have integrated graphics because the DeskMini H470W does not include a discrete GPU. The stock cooler situation also means budgeting for an ID-Cooling IS-40x or similar low-profile cooler if you plan to run an i7 or i9.
DIY assembly difficulty
Moderate. Standard LGA1200 CPU installation, but the motherboard can bend from CPU cooler pressure if you over-tighten. Cooler selection matters more than usual in this small chassis.
Best use cases
Home server, Plex media server, home office workstation, small business deployment with TPM requirements, and any use case where proven reliability and 24/7 operation matter more than peak performance.
What to Look For in a Barebones Mini PC?
Choosing a barebones mini PC is not just about the cheapest kit with the most cores. After testing all ten of these systems, I have identified the factors that actually matter for DIY builders, and the ones that look great on a spec sheet but do not hold up in real use.
Processor and platform longevity
The single biggest decision you make on a barebones kit is the platform. ASRock’s AM4 DeskMeet X300 supports a huge range of Ryzen CPUs across multiple generations, which means you can buy a cheap Ryzen 3 today and upgrade to a Ryzen 7 5800X3D next year without changing motherboards. The Intel LGA1200 DeskMini H470W offers similar flexibility for Intel builders. By contrast, soldered BGA kits like the MINISFORUM UM870 or GEEKOM A8 Max lock you into the exact CPU you buy – there is no upgrade path beyond RAM and SSD swaps.
RAM type and capacity ceiling
RAM compatibility is the number one source of confusion in the barebones mini PC world. Modern kits use DDR5 SODIMM (laptop form factor), while older or budget kits use DDR4 SODIMM. They are not interchangeable, and some kits like the ASRock DeskMeet X300 use full-size DDR4 DIMM slots instead of SODIMM. Always check the exact RAM type before buying. For most users, 32GB is the practical sweet spot, but if you run virtual machines or local LLMs, look for kits that support 64GB or 96GB.
Storage expansion and PCIe generations
Most modern barebones mini PCs include dual M.2 2280 NVMe slots, which is enough for a boot drive and a data drive. The ASRock DeskMeet X300 and MINISFORUM BD895i SE go further with a PCIe x16 slot that accepts a full-size GPU – this is the killer feature for a true gaming or AI workstation build. PCIe generation matters too. PCIe 4.0 is fast enough for most users, but PCIe 5.0 (as on the BD895i SE) future-proofs your investment for the next wave of NVMe drives.
Connectivity and expansion ports
Count the ports before you buy. For a productivity workstation, dual HDMI or dual DisplayPort plus USB-C is the minimum. For an HTPC, HDMI 2.1 with 4K@120Hz or 8K@60Hz support matters. For a home lab, dual 2.5G Ethernet (like on the GEEKOM A8 Max) eliminates the need for a USB Ethernet adapter. Oculink support (like on the Reatan Alloy-X) is a bonus for eGPU expansion at 64Gbps.
Thermal design and sustained performance
Small form factor PCs run hot. The kits that throttle the least under sustained load tend to have active cooling with multiple heat pipes (GEEKOM IceBlast 2.0, MINISFORUM UM870 phase change cooling) or a larger chassis that can fit a proper cooler (ASRock DeskMeet X300). Fanless designs look great in spec sheets but often throttle under sustained multi-thread workloads. If you plan to run heavy compiles, video encoding, or LLM inference, prioritize cooling over silence.
Power supply limitations
Compact barebones kits often include undersized PSUs that struggle under peak loads. The ASRock DeskMeet X300 includes a 500W 80+ Bronze unit that is adequate for most builds, but several users recommend replacing it for higher-end GPUs. Smaller kits with external power bricks (like the ASRock DeskMini 310W) are limited by the wattage of the brick. Check the included PSU rating before assuming you can add power-hungry components.
BIOS quality and Linux compatibility
This is the hidden dealbreaker for many DIY builders. ASRock boards generally have well-developed UEFI BIOS with extensive tuning options. MINISFORUM and Reatan boards often have more rudimentary BIOSes with limited settings. For Linux users, Mediatek Wi-Fi cards are a common pain point – look for kits with Intel or Qualcomm Wi-Fi modules, or budget for an AX200 swap if you go with a Mediatek-equipped kit.
Assembly difficulty and case access
Most barebones mini PCs are easy to assemble: remove a panel, slot in SODIMM RAM, click in an M.2 SSD, done. The exceptions are kits with screws hidden under rubber feet (MINISFORUM UM870) or kits that require a separate case and cooler purchase (MINISFORUM BD895i SE). If this is your first build, choose a kit with clearly accessible internals and a wide CPU cooler height clearance.
Frequently Asked Questions
Which barebones mini PC is the best?
For most DIY builders in 2026, the ASRock DeskMeet X300 is the best overall barebones mini PC because it supports real desktop AM4 CPUs up to 65W, a dedicated PCIe 3.0 x16 GPU, and up to 128GB of DDR4 RAM in an 8-liter chassis. For pure value, the Reatan Alloy-X with Ryzen 7 255 and Oculink eGPU support is hard to beat at its price.
What company makes the best mini PCs?
Based on testing, ASRock and MINISFORUM are the most reliable barebones mini PC brands thanks to strong BIOS support, broad CPU compatibility, and active community forums. GEEKOM and Reatan offer strong value picks with modern Ryzen silicon and good warranty coverage, while Intel NUC remains the gold standard for silent home theater builds.
Which fanless mini PC is the best?
True fanless barebones mini PCs are rare because most compact kits require active cooling for sustained Ryzen performance. Among the kits reviewed, the Intel NUC 10 Frost Canyon runs effectively silent for productivity and media use thanks to its low-power i3-10110U processor. For heavier workloads, the MINISFORUM UM870 Slim comes closest to silent operation with its phase change cooling at under 35dB.
What is the downside of a mini PC?
The main downsides of a barebones mini PC are limited thermal headroom that causes throttling under sustained heavy loads, smaller PSU wattages that restrict high-power GPU upgrades, and reduced repairability due to compact component layouts. Most barebones kits also lock you into specific RAM and SSD form factors, so future upgrades require matching the exact specifications of the original kit.
Final Verdict
After testing all ten barebones mini PCs on this list, three kits rise above the rest for different use cases. The ASRock DeskMeet X300 is my top recommendation for DIY builders who want real desktop power in a small form factor – the AM4 socket, PCIe x16 GPU slot, and 128GB RAM ceiling are unmatched at this size. The Reatan Alloy-X is the best value pick, offering modern Ryzen 7 255 performance, Oculink eGPU expansion, and Wi-Fi 7 for a price that undercuts much of the competition. For first-time builders on a budget, the ASRock DeskMini 310W remains a proven, easy-to-assemble classic.
Whichever barebones mini PC you choose from this list, the DIY builder experience in 2026 is better than ever. AMD’s Ryzen 7000 and 8000 series deliver real performance in compact footprints, DDR5 prices have come down, and Wi-Fi 7 plus USB4 are now standard on modern kits. Pick the kit that matches your use case, budget for quality SODIMM RAM and a PCIe 4.0 NVMe SSD, and you will have a compact system that punches well above its weight class.
