Wang
I used to have a Wang OIS-50 from an old job. The RMU board was shot, and I didn't have a terminal anyway.
I had at one time entertained the thought of using it as a PC case, but then I thought "nah, that would be a lot of work to modify it". Seeing the sorts of "case mods" done since I got rid of it, I expect it would have been a cinch compared to what some folks have done.
