Here is what it looks like. Note the switch, and light placement.
I decided to make my old Dell (now a linux box) some bling(ish) so I grabbed some LED's, a switch, a terminal block, and some wire, a molex, and some resistors. You only need one (value depending on 12 v or 5 volt--I had 6 because I did not have a correct value) Very simple mod, but soldering skills were required. I just hotglued the LED's to the front panel of my case, and drilled a hole for the microswitch. A $10 mod that is very simple and looks very good.
