This Digi 002 Rack works fine, however it won't work with newer Mac Operating Systems, so make sure this'll work with your system before purchasing. Software included is demo software from Ableton and Reason. Pro Tools is not included. I've used this rig for a good number of years in a smoke-free project studio. It has been rack mounted, but it's in great shape. Missing one knob and another is kinda squished. You can see in the photos.

Here's what Digidesign has to say about it:
