Now I want to install A/UX on my Quadra 700! I really wish I had kept my 650 from when I was a kid. That thing ran Marathon 2 like a champ.

IIRC, the bad part of the 650 case was the cover. The ability to have a tray CD ROM in the box was nice. If there had been a separate cover and front bezel, it would have been a lot better. The clunky bezels are usually the first thing missing/damaged from any old system I come across.
