RE: UP2000+ Problems

Will, list:

The PSU I used was the Enermax EX465V AX-VE(W.  It has the Aux 6-pin connector
as well as the 4-pin and the ATX connector.  I ran the board bare, no case,
with an off-brand Permedia 2 card, no other peripherals. 

I was able to load and run some of last year's Fedora "distros" on it before
donating it to a guy in Austria who I thought was going to use it helping out
on the Fedora project.

It was just too hot and noisy ...
