yes i am. those cards are not some cheap ati 5xxx cards, they are 6990 that cost 5000 norwegian krones each and those cards give me 1670 Mhash/s.
and by the way, good luck keeping 50 cards overclocked and cool in a closet at that size.


thanks... you should put whole on the case so the heat goes out and not cycle inside the case. and 1 powerful fan like mine is enough to get cool air from outside...
