Hey, i've recently built a similar system to yours...it was my first self build and i'm quite pleased with it. Asus P6t deluxe intel i7 920 antec p182 Asus HD4670 + Arctic Cooling Accelero S1 rev 2 6 gb ocz 1333 2 samsung spinpoint F1 750gb (soon to be RAID 0) enermax pro82+ 625w TRUE + 2 noctua NF-...

I'd be interested to know which passive coolers or near silent active coolers work with this card. I've bought an asus hd4670 and want to get rid of the noisy fan. If anyone has any tips???
