At first I wanted to make a case out of sheet aluminium, custom made at a local case manufacturer.

Then I thought maybe I need to just 3D print something, 'cause of course I didn't buy the IPEX-equipped ESP32s this time so WiFi won't pass through the aluminium.

(Here's the Onshape workspace, by the way, in case you need the PCB sizes or a decently accurate SFF-spec CD-ROM drive size model)

But in the end, ultimately, I just bought a bunch of MDF sheets that looked like they were a suitable size, and some corner brackets which happened to fit perfectly, and here I am again making a 1970s case for a 1990s device rebuilt in 2025.

The PSU is now internal since I demolished an old broken DVD player which happened to have a suitable one, and despite having the insulation sheet on the primary side of it I'm still thinking I should probably do some fire-retardant coating on the inside, just in case.
