I have been thinking of running Tomato firmware on my wrt54g in order to increase the range of the wifi and using QOS for streaming video around the house. One post I read mentioned that heat might be an issue and since I have not done any modding or soldering for months it seemed like a perfect little project. The 60mm fan and rheostat is total overkill but I really hate the high pitch whine of a laptop fan. I thought of soldering the fan straight to the board but that would have meant cutting the wires next time I want to open it up. This way I have fan control and quick disconnects. I am not going to post screen shots of setting up Tomato because there are much better tutorials than I can make with my limited experience with it. Bigger pictures are here.
