Andromeda sold some cool Q-bus chassis with drive mountings and power supply integral. I
think the one in the E-bay auction is two 3U sized cabinets either just sitting on each
other or maybe screwed into each other.
One cool Andromeda product that was available for a while in the mid-90's, had power
supply, room for a few 5.25" and 3.5" drives (I think by default with hot-swap
caddies... that may have been just added on though), and a Q-bus chassis all in a desktop
small PC-clone style case. With just two cards (a Mentec CPU with 4MB memory and serial
lines + an Andromeda SCSI controller + Ethernet, a tape drive, a floppy, and a couple
hard drives) it was a neat, almost laptop-sized PDP-11 development environment. That came
in really handy when I was traveling all the time.
