It is very siomple in itself. You just need a bi-color LED, preferably a 3-pin LED, RED/GREEN, and two small cables with the ends having flat plus that fit over the PC's front panel indicators. Try with 330 ohms, but if they are too dim, you do not need them. The output of the front panel connectors has current limiting built-in, so the bi-color LED can be connect directly without current litiming resistors. See my diagram below here.

The bi-color LED can be purchased at Radio Shack, or online here...

If you use 2-pin bi-color LED, you will need more complicate driving circuit.

Hope this help.
