Best SteamOS Mini PC of 2026

If the word 'later' is part of your SteamOS plan, start with the OCuLink port on this one. It lets you add an external desktop graphics card over PCIe 4.0 x4, which is a different kind of upgrade from swapping a stick of RAM. Around that port, the UM880 Plus packs a Ryzen 7 8845HS, Radeon 780M graphics, 32GB of DDR5, and a 1TB SSD.

We appreciate the headroom. 32GB is more than SteamOS needs today, but it leaves room for a Windows dual-boot, a Linux VM, or a game server running alongside the desktop. The 8845HS is a known quantity in this class, and the 780M is the same graphics class as our top pick, so the gaming experience is in the same neighborhood. The triple display outputs and 2.5G LAN are useful if the box is also your desk computer. This is the most complete machine here out of the box, and the one we point to for an eGPU setup.

The catch is Linux Wi-Fi. The installed MediaTek card lacks Linux drivers, so a SteamOS install may come up without wireless. Use Ethernet, which the dual 2.5G ports make easy, or plan to swap the card. That is an annoying extra step on a premium machine, but it does not stop it from being the best pick for an eGPU setup. If you already own a graphics card and want a small SteamOS console that can grow, this is the one.

At 550g and 130mm square, this is the smallest serious 780M machine in the group. It can sit on a VESA mount behind a monitor or slip into a bag with the power supply. That makes it the pick for a SteamOS setup that moves between a desk and a TV rather than staying put.

It still has the hardware that matters: a Ryzen 7 8745HS, Radeon 780M, 16GB of DDR5, a 1TB NVMe SSD, and an OCuLink port for an external GPU. The dual 2.5G LAN and quad display support are more than you need for a console, but they make the A8 useful as a small workstation too. We like that Reatan did not strip the port selection to hit the size.

The caveat is setup. A BIOS update has been needed on some units to get the graphics working properly, so do that before you install SteamOS; otherwise you may be troubleshooting a problem that is not Linux's fault. The A8 also costs more than our top pick for the same 16GB/1TB layout, so the size and OCuLink need to matter to you. If they do, this is a good fit; if not, the Getorli is the easier recommendation.

Most mini PCs hide; the Retro X3 wants to sit next to the TV. The case borrows from a classic console, and that is not just decoration: a SteamOS box in a living room is visible, and most mini PCs look like networking gear. We like that ACEMAGIC gave it a personality.

The hardware is not retro. The Ryzen 7 H 255 and Radeon 780M are the same core combination as our top pick, and the 54W TDP is higher than some machines here, which should give the graphics more room under sustained load. It also comes with 16GB of LPDDR5 at 6400MT/s and a 1TB PCIe 4.0 SSD, plus HDMI 2.1, DisplayPort 2.0, and USB4 for triple displays. That is a sensible living-room spec.

The memory is the trade-off. It is soldered LPDDR5 capped at 16GB, so there is no adding a second stick later. For SteamOS gaming, 16GB is enough today, and the faster memory speed helps the iGPU; you just have to accept that this is the configuration you are buying. If the case will sit in sight and you do not plan to upgrade, the X3 is a more engaging choice than a plain black box. If you want to tinker with memory later, go with the Getorli.

Four 4K outputs is more than a SteamOS console needs, but it is the reason to look at the Glorlin GT105. The rest of the spec sheet is sensible: Ryzen 7 8745HS, Radeon 780M, 16GB of DDR5, and a 1TB NVMe SSD in a 1.1kg chassis.

We see it as a desk-first SteamOS PC. If you want one small box for a 4K monitor, a TV, and two work screens, the Glorlin makes sense. The 780M is the graphics class we look for, and the 8745HS is close enough to the 8845HS that the difference is not the main story. The four outputs are the main story. They are useful for productivity, but they do not make it a better games console than the top pick or the UM880 Plus.

What you give up is the light travel build and the top pick's lower price. The Glorlin is a 1.1kg desk machine, while the Reatan A8 is 550g and the Getorli costs less. If you need the display count, it earns its place; if you do not, the simpler 1TB machines are the better buy.

Linux support is the reason to consider the P6. It ships with Windows 11 Pro but is built to run Linux, and an Ubuntu Server install has come up with the NIC, NVMe, and Wi-Fi recognized. For a SteamOS shopper, that is a useful head start: you are less likely to spend the first evening chasing a driver.

The hardware is a step sideways rather than forward. The Ryzen 9 6900HX is a strong eight-core CPU, and 24GB of LPDDR5X plus a 1TB PCIe 4.0 SSD is generous, but the Radeon 680M is a class below the 780M machines here. It will handle SteamOS at 1080p with settings turned down; it is not the one to pick for high-refresh or 1440p gaming. The three 4K outputs and dual USB 3.2 ports are useful for a desk setup.

We like the P6 for a dual-purpose build: a Linux desktop or home server that games on the side. The soldered 24GB memory is the ceiling, so buy it for the memory you need now, not the memory you might add later. If gaming is the main event, the 780M picks are worth the step up; if you want a Linux-first box with more RAM and a 1TB drive, the P6 is a sensible alternative.
