My computer is about as loud as a vacuum cleaner due to all the fans it has and it's really annoying. I wanna make it silent by getting a new case, fans, etc.. basically a whole new cooling system.

My question is: what would you choose as the quietest setup possible that can still cool everything properly? keep in mind that I have a Athlon T-Bird 1.4ghz (really hot) and I wanna keep it at 40 to 50 degrees celsius or less. I also have 4 hard drives which put out quite a bit of heat and a GeForce 3. so I would prefer if the case has some cooling in the front. I also want to keep this case around for a long time, so it has to have lots of room to expand and more possible cooling options for a later and hotter CPU.

would you go with water cooling? or is a water cooler really loud too? what heatsink + fan would you use for the athlon? gimme a whole setup that you think will do the job.

price is not that important for me.. but the cheaper the better.

thanks.
