[linux-audio-user] Quiet PC Components?

Hello, I have been playing with DRC and Brutefir for room correction and digital crossover capabilities. The results have been positive and now would like to quiet down one of my PC's in order to keep it in my stereo system. I am looking for a particularly quiet case, CPU fan (for Athlon 64), and a video card that does not need a fan (hopefully NVidia based or something that is easy to configure in Linux). I can't afford the expensive fanless PC cases (heat pipe style). For those who have tried to silence their PC, any information on the component brands and model numbers that you have had success with would be much appreciated. Thank you, Alan
