A couple of LEDs would be more than sufficient, even better if you can make a "light bar" out of a piece of thin perspex or something to carry the light more consistently. You could power the LEDs off the USB port, assuming they are 5V.
There is a bit of space under the PB Ti's keyboard where you could fit all this.
I'm playing with my PB Ti as well at the moment - it was an 867@1067, but bought a $20 junker 1000Mhz model (which also has 64MB VRAM over 32 of the other board), hoping to put this board in there @ 1200Mhz. It would make for quite a fast unit, I think the Ti model has a better G4 over Alu models (more cache etc?)?
