what to make fan duct with?

[Cerb]

I'm working (or rather, my arm is sore, so I'm waiting til I can work again) on turning an old tape player into a computer. I want it to be no louder than the stereo system next to it (crappy Aiwa). So Ideally the whole thing will be cooled off by one case fan (the PSU is mostly going to be open). Since I will have very little, if any, room to play with, what would be a good thin, stiff material to make a fan duct out of? Ideally I would be able to measure, make the duct, install it while I make the final install of the rest of the parts, and then leave it. The hottest thing is the CPU, a celery 466 (but I want to upgrade it to a PIII 700 or so to play high quality DivX).

Cerb, I saw some of that "flexable" tubing at my local Home Depot, that might be a place to start, hope this helps a bit

Yeah, I'd look for some of the drier vent tubeing or PVC elbows, etc. If you were to get a dual fan PSU and mount the "into PSU fan" at the end of the vent, I bet you can pipe all your CPU air through that and keep a reasonable temperature. I'd look carefully for ducting without a metal spring/reenforcement in it (some have fiberglass).
