I had a SGI O2 years ago that I bought off some estate auction but I couldn't ever get it running as stable as I'd liked. Intended to use the case for a casemod project, but in the end I sold it off for what I got it for to someone that had more interest in getting it running in daily driver fashion than I had.
Just didn't have the heart to gut the case and throw a PC mobo in it, but I always loved those cases and still dream of stuffing a real nice smaller PC mobo into one of the SGI shells.
