“An open source 3D printable PC case that can fit your components exactly by adjusting a few parameters.
The case is fully built out in OpenSCAD, an open source parametric modeling tool http://www.openscad.org/
You can generate printable stl files from that quickly by adjusting a few parameters to match your components.
If you happen to own the same components as I do (Noctua NH-L12s, Zotac 1080 Mini, SFX PSU), you can also just use the example stl files directly.”
