I while ago I bought this very nice kit

and assembled it.

I quickly realized that I'd like a box behind the PiDP, and it would have to be a heavy one so that I could handle the buttons without the machine toppling over.

Another reason for a box was that it'd allow me to tuck away cables and power supply more conveniently. E.g., got around the problem mentioned on https://obsolescence.wixsite.com/obsolescence/pidp-11-connectivity-options about the usb connector being too deep.

The main reason, however,  was having a fun project to work on :)
