Becomingmass, a member here, and also a really good friend of mine has a broken GTS 450 that he had been using for a PhysX card, but now that it's broken it is just sitting in his room. Maybe when he moves in October or whenever he is moving, he will be willing to dump it off to me. I could probably take off the heatsink and fan (the broken part), and put either an Arctic air cooler on it, or maybe even grab a universal GPU block and a rad and pump. I find it really sad that it is more likely that a card I would use for folding would get water cooled before any of my main rig even gets a little wet.
