The server was a Prosignia, but that's quite possible, too, I suppose.  I 
no longer have the system, but I do recall that the cooling in the room 
wasn't very good (it was my house, but the computer room was a southern-
facing room here in Utah, and the problems were always during the summer 
months).  Oh, and the power was intermittent in the system as well, so it 
could've been a bad PSU.
