The Sunbeam Lightbus is really a nifty device and one that I'm kind of surprised hasn't been copied by anyone else. The fact that it can also be used to control fans is just icing on a pretty sweet cake! The only things I see that could be improved upon are making the hard drive connector a pass-through one so the cases HDD activity light can still be used, and finding a way to utilize the motherboard's or sound card's headers for accessing the sound signals, rather than using a pass-through cable that will have to be strung all the way across the interior of your case and out the back.
