I'm sorry I don't have any pictures of the one I did (my digital cam is busted

), but I'll try to be really descriptive, so use your imagination!
Szech sets the mood...
My mother's processor fried (Celeron 566@850, 1.8v). I don't like when her computer goes down because I'm the one who gets to repair it. After I figured out it was heat related, I was going to watercool her processor, but I can't imagine what kind of grief I'll hear about if anything ever went wrong. She has bad airflow, because she insisted that the case fans were too noisy, so I figure that a duct would be a good way to go. I'm sure that what killed the processor was recirculating air in So-Cali summer heat.
An idea is born...
I got a 3" flexible aluminum dryer duct, a 3" aluminum duct connector (they look like 3" O.D. tubes) and two 3" hose clamps. I took all the components out of the case, and took it to work where I picked out a 3" hole saw. My coworker commended me on my dragon cutout

. I put the case on the drill press, lined it up to the existing holes in the front, and cut all the way through. I didn't plan on it, but the duct connector
barely fit through the hole. It's so snug that I didn't have to use any adhesive to hold it in place. The processor has an orb (I know, I know... ), which made it pretty easy to attach the duct. Because the diameter of the orb was less than the duct, I wrapped a thin strip of rubber around the top three times and taped it in place. I put the duct in, and tried to tighten the clamps over the orb. It doesn't work. I took the orb off the processor, clamped the duct over the top, then led it to the connector in the front. Yay! It does take a good amount of real estate in the case, but if it saves me another repair trip, it's worth it (not that I don't like seeing Mom, but repairs suck

). The temperatures don't go over 41C in a hot room during a So-Cal summer, so I know it's doing its job. Also keep in mind that this is in a case with
two fans (the Orb's and the power supply's), which makes it that much more impressive.
I'll try to get some pics up. I like my work on this particular project
