Yes I have this 3 led mod (they are green only leds like the original LE and topper). I have them positioned under the dvd boxset fishtank that was available a while back. Its awesome. I don't know how you would use RGB lights here. There is no support for them, you'd only get green.
Here is what I and several others have done on our pro.
Quoted from Gamemodder:
Thank you. But It doesnt have exactly what I need. Im trying to make this for my pro, but with the actual rgb lights.
