As to Home Depot, that'd be a long trip as I'm in Sweden
Go to IKEA and buy something from the kitchen section. :) Maybe they should start selling an empeg cooler?
I think it may be a good idea to start reading the other "chilling" thread about mounting a fan. It's possible to mount a small fan inside the empeg or even a slightly larger one to the sled.
Some of the laptop prototypes I use here at work have really nice, low noise, small fans in them. I'll look at a couple of them next week to see if I can get an manufacturer or part number info.
