I've got one better than that:
I've seen a half-height rack enclosure, that had rack mount on the front, vertically, and a slanted rack mount area on the top, (try to picture it).
My idea is this:
A Tascam 38, mounted (vertically) in the bottom rack/bays. Then, two DX-4D dbx units, rack mounted above that. Then rack mount compressor, reverb, delay unit, and patch bay (discrete). Top this off with a slant-top-rack-mounted Tascam Model 30 mixer, 4 heavy duty WHEELS, 4 heavy duty HANDLES, and it's the:
SUPER-DUPER-RETRO-PORTA-MEGA-STUDIO
I'm not joking, I'm serious. I'm going to make one just like I've described. Tascam, eat your hearts out!
