A dual 1.45GHz POWER4+ barebones Intellistation is turned its side, POSTing. With the cover on, it isn't as loud - there are noise mufflers available for it too.
@randomshinichi it was on for $1400 and I offered 1000 and they took it! It was a good deal but I think its not enabled for PowerVM(aka APV) IVM or LPARs etc
