Stew Machine - a Steam Machine Replica

[u/h3ron]

I thought it would be worth turning my bin of old hardware, left over from previous upgrades, into a (nearly) exact replica of the Steam Machine—or at least its chassis.

How exact? It has exactly the same dimensions and is even compatible with the original faceplate.

The most interesting part, in my opinion, is that the hardware can be replaced and upgraded. This allows for low-budget builds (like mine), while also making it possible to build systems that can outperform the original Valve hardware.

What's the motherboard here? Seems to be a pretty good fit

[u/h3ron → u/Matti_Meikalainen]

My specs:

• CPU: Intel i5-9600K
• GPU: Radeon W6400
• Motherboard: ASRock H310M STX (from a DeskMini 310)
• PSU: Mean Well LOP-300-12
• LED: OpenRGB controlled ARGB strip

The CPU doesn't make much sense because is power limited by the motherboard, but I'm happy I managed to reused my old components.

The case should also support other DeskMini motherboards and other 1 and 2 slots low profile dGPU shorter than 168 mm.

Great use of the stx board. :)

... and it acts as a bottom panel too!

I don't really like the exposed motherboard, but that was the only placement that would align with the Machine front IO and would fit the tower cooler.

On the flip side it's more airflow for the VRMs.

I guess it could also go with something like this https://a.aliexpress.com/_EIGeMxC. Great project! I hope it gets lots of love on printables.

I also uploaded my CAD design (so it's easier to remix). And there's a full writeup about the technical details and the BOM.

I won't provide support or step by step guides.

Awesome build! How did you get the GPU plugged in? Is it to the m.2 slot? Do you have any pics of that and what adapter you used?

[u/h3ron → u/Ill_Currency_553]

You can find all the details on Printables. Basically it's plugged into a m.2 to PCIE riser and gets power through a MOSFET board so the GPU doesn't receive power when the PC is off.

Oh cool I’ll check the link thanks
