You should really use the negative of the power supply you get 12 volts from, as the ground on the motherboard is for 5 volts so the PCB tracks are not as thick, using them for 12 volts could cause damage.

Nice instructable. The clear circuit schemes are helpful to understand the electronics of our PCs.

I take it you got a VU meter by salvaging it from a stereo or something. Nice that you turned it into an instructable.
