OK, I own an Xbox Crystal with a mod-chip in it. I've discovered much more uses on it than playing games on it, like modding the dashboard and other stuff.
My question is, is there ANY difference between the normal Xbox and the Crystal version? (other than the whity-ness?)

No difference man. The only difference is the colour. It's just like when N64 relased their donkey kong green system. It appeals to a larger audience.
