Ok this ain't really the most Mac related comment but it kinda does concern a Mac. I am just about finished building my new desk. I have tried alot to hide the cables and the powerbrick from my Xbox 360 and iBook. The plugs + powerbricks are going to be put in a wooden enclosure to hide them away. The only problem is the heat issue. I want to put two 60mm fans on the top of the enclosure but I also want to power them from usb if possible. The problem of course is how do I get from the 4 pin power plug on the fan to a usb connection? Help would be much appreciated. Cheers.
