Neat...btw; mine hasn't revved since the first release. I'll have to pickup one of those IR receivers...seeing this gives me some interesting ideas; I never even thought of putting stuff behind that panel.

EDIT:
Ok its been on over an hour now and i've tried a few different games and the temperature peaked at 51 and settled at 50 while playing, i'm sure it would go higher playing COD. The most demanding game i have on it is Burn Zombie Burn.
2) The music reaction is done with 2 TIP31a transistors. The sound from the motherboard is connected to the base of the first transistor. That transistor has 5v going through the collector - emmitor. the emmitor of the first transistor is connected to the base of the second. The second then has 12v going from collector to emmitor. The LEDs are connected to the collector leg and the emmitor is grounded.
There is a third transistor used as a switch which the arduino controls to put the LEDs into reactive mode.
Hope you can follow that, ill try again if not.
3) You are asking about the hardware, not the libraries. OK. I used a TSOP4838 Infrared Reciever 38kHz. Since i snapped of almost all the pins on the translucent case of the ps3 i put the reviver in one of the holes on top of the blu-ray drive. It still get good signal across the room through the lid.

It's at the bottom right ish.
You wouldn't want this one
