This is a design I created for an old firewall motherboard that I rescued and turned into a Windows 98 PC for retro gaming. I wanted it to have a design reminiscent of a typical 90s PC, but at a miniature scale.

The mounting holes in the chassis and the cutouts in the back plate are custom made for this particular mobo, so those parts would have to be modified to host something else.

The dimensions of the firewall mobo used here is about 15x20 cm.

If you're curious about the build I designed this for, here's a video I made about it: https://youtu.be/rYiW8kq2aTs
