Cramming A Mini-ITX Gaming PC Into A 3D Printed Steam Machine Sized Case

June 27, 2026 by 22 Comments

The recently released Valve Steam Machine is somewhat awkward in that it uses a custom, non-standard PCB and non-standard power supply. This fact apparently has irked some people who decided that it makes perfect sense to try and cram a Mini-ITX board, Small Form Factor (SFF) PSU and full-sized discrete GPU into an enclosure of the same size. Cue the SFF Mini-ITX Steam Machine Case project by [3DCatt] over at Printables.

This is apparently a project done in cooperation with AMD’s [Jacob Terkelsen], who showed off the 3D printed case stuffed full with the aforementioned parts, which includes a GeForce RTX 5060 GPU. Of note is that the Valve Steam Machine uses a different cooling configuration as it has both the CPU and GPU on the same PCB. These share the same massive heatsink, as can be seen in e.g. the [Gamers Nexus] teardown video.

For this angular imitation machine it would have been nice to use a blower-style GPU, to exhaust the hot air rather than dump it all into the case. This is also an issue that was raised by [Jacob], with more ventilation added to mitigate the issue. What the overall performance will be compared to regular compact Mini-ITX cases remains to be seen, but if you really want to live the Steam Machine life and have some parts kicking around along with a 3D printer, it might be worth a shot.

A Steam Machine Clone For An Indeterminate But Possibly Low Cost

For various reasons, crypto mining has fallen to the wayside in recent years. Partially because it was never useful other than as a speculative investment and partially because other speculative investments have been more popular lately, there are all kinds of old mining hardware available at bargain prices. One of those is the Asrock AMD BC250, which is essentially a cut down Playstation 5 but which has almost everything built into it that a gaming PC would need to run Steam, and [ETA PRIME] shows us how to get this system set up.

The first steps are to provide the computer with power, an SSD, and a fan for cooling. It’s meant to be in a server rack so this part at least is pretty straightforward. After getting it powered up there are a few changes to make in the BIOS, mostly related to memory management. [ETA PRIME] is uzing Bazzite as an operating system which helps to get games up and running easily. It plays modern games and even AAA titles at respectable resolutions and framerates almost out-of-the-box, which perhaps shouldn’t be surprising since this APU has a six-core Zen 2 processor with a fairly powerful RDNA2 graphics card, all on one board.

It’s worth noting that this build is a few weeks old now, and the video has gotten popular enough that the BC250 cards that [ETA PRIME] was able to find for $100 are reported to be much more expensive now. Still, though, even at double or triple the price this might still be an attractive price point for a self-contained, fun, small computer that lets you game relatively easily and resembles the Steam Machine in concept. There are plenty of other builds based on old mining hardware as well, so don’t limit yourself to this one popular piece of hardware. This old mining rig, for example, made an excellent media server.
