I was thinking of buying one of them as well.
Because i was trying to make my pc silent.
But, i came to a conclusion, I mostly use headphones with my rig so why the heck does it matter!!!lol.
So i just brought a standard Sapphire 9700PRO card.
If you really wanted one, but couldnt find somewhere that sells it,
then buy a standard 9700pro card, and buy the zalman HS seperately.
