Yeah this would invalidate my warranty but it' s a 2 minute job as the 360' s case comes off easily and the metal box that contains the kit would simply fit into this case, then snap the matching faceplate on.
They do...
Gold
Chrome
Clear
Blue (clear)
Halo Green
Black with blue X LED
Black with green X LED
...and they' re going to release a Metallic Green case...
...and more stuff to invalidate you warranty like...
LED' s for the fans
Cool yet wierd looking LED' s for pads
...and other stuff.
