There's nothing hard to it.
It's really basic, just wire the leds to the PVU2X and the power/ground to it.
My suggestion is use a battery pack instead of the PSU or motherboard for power (Keep it nice and safe, know what I mean?).
Sickmods has install diagrams for the leds and power/ground so just follow that but instead of wire to a wii or something, just wire to a general point.
Good luck!
