It’s been a while since I owned a Sun Ultra 5, back to 2002. It has run many OS, mostly BSD flavoured, and served me well in many cases. It has been tweaked a bit: add a Quad HME card, replace the CD-ROM by a CD-RW burner and replace the fan and PSU by silent PC parts.
I’ve just powered it on and it is indeed quite silent. I really would like to use it again… if it wasn’t needing 61 Watts (more than a Mac Mini G4). So here we are, a last OpenBSD install before I find a new home for it.
