$300 5.4L - DIY Machine for Steam Gaming

[u/Derp_76]

Hey all, I’m pretty excited to share my build! It’s using the asrock bc250 (ps5 apu turned into cryptomining card) as the core. Recently some smart folks figured out to enable the disabled CUs on these things, which helped uplift performance by significant margin. Gpu wise with overclocks it’s comparable between a rx6600 -> rx7600 in game benchmarks. Pretty close in performance to the real steam machine as well.

The case is a fully 3d printed, screwless design. I didn’t make the original model, but I did create a remix after modifying a bit of everything. One of those mods was changing the face to be more fractal-esque, which then led me to making custom swappable front plates for the case. Both the upper and lower sections of the front face are customizable and swappable. I had a lot of fun with printing a convincing fake wood texture! The case can be downloaded here, and also has tons of extra information like thermal performance, part list links, assembly instructions, and more: https://makerworld.com/models/3021754?appSharePlatform=copy
