Ok so I ordered this nice fan from xoxide.com

Looks boss right? Well turns out that the side u see in that pic you will not see if you install the fan in the xbox. So I salvaged a little fan off a car stereo and a fan of a heatsink. The one off the heatsink is taller than the one from the car stereo. So I figure if I put the smaller one under the DVD drive on the left side and the larger fan on the right side. I belive the one on the right would help cool the psu and HD and the one on the left will take out air. THis way I can install the 80mm fan to show the above side. Any one thinks that this will work?
