Just stopped by to let you know I got it and (finally) have it set up. I had to hack a molex to work (to get the extra 2 ground pins). Then, it wouldn't let my pentium 4 moboard boot... so I moved it to the x4 AMD ex-server.
I've got it running ... omghfc that thing runs hot. The instant it started folding, it went to 103~104Â°C !!! Granted, it's about 90Â°F ambient, but the other computers are doing OK. It has unexpectedly username and passkeys. One of the 9800GTs is sitting on the bench and the other one got switched back to ca-cycleworks.com.
Trippy card. Heavy industrial metal enclosure. I am going to try and get HFM working... hopefully can get to that tomorrow. I'm in whack-a-mole mode at work and I get grumpy when I'm that behind.
