I'm not so fond of the acrylic style cases because they're not scratch proof, impact proof, nor chemically resistant. I like to build stuff that lasts "forever".
For the n0nx0x project, I did a small group buy for aluminum frontpanels, which was very affordable when ordering +20 panels:

Those panels are scratch and chemical resistant. But of course thats only the front panel.
A panel like that (in the appropriate 808 style), combined with a sturdy plastic or a nice wooden sides case, would be lovely.
I guess something like the Hammond 1441-32BK3CWW may fit, though a bit wide. I'm sure there's other options, this was just the first site I checked.

Anyhow, I wonder if anyone else is doing something like that.
