Hello,
I released a project for a full desktop cabinet (CPU, PSU, Floppy disk drive) for the micro_8088 computer. I made it suitable for the Creality Ender 3 Pro, so it should be ok for most printers (it requires a printer with at least 220x220 mm print size).

There are two flavors, a smaller one that will fit perfectly the micro_8088 and all the Sergey's cards, and a bigger one that can also host the LPT + COM card by hkzlab.
Hope this would help!
