Snap On primarily sold the testers individually that you see housed into the cabinet. They just grouped them all together ... put them in a cabinet and called it a diagnostic center/machine. You could get the test units individually housed just in the little metal case or you could get them mounted on a stand with wheels.

I'm guessing value is not going to be very high ... probably more money in popping them out of the cabinet and selling them that way I would think. Unless you get someone wanting to do a full resto on the whole unit.
