Silent PCs With Thermoelectric Panels?

pdxChris asks: "I'm assembling a new PC for digital audio recording and music production. I'd like this machine to be absolutely silent, with no fan noise at all -- actually, no mechanical noise of any kind outside the hard drive spinning. While browsing at an ecology products vendor I found information on thermoelectric panels: they pump heat from one side to the other when supplied with DC, without making any noise. As this is new to me, I did an AltaVista search for more information on the topic and found a nice overview. I'd like to replace all fans in my new PC with thermoelectric panels, so that the machine could be right in front of me (for swapping audio cables, popping in new blank CD's, etc.) without making any sound at all that could distract from the music or be picked up by my microphone. As for the hard drives, perhaps I could put them into an external SCSI case with an extra-long cord to get them into the closet I'm willing to put up to a few hundred dollars and a few dozen hours into the project if it's feasible to obtain a totally silent PC!"
