Thats a pretty sick pc mod. I haven't really heard of anyone changing their buttons. Apple's buttons are so slick already it would be hard to make a better one. However, it could be possible to change the color on the powermacs. I am not too sure how you would go about it. I will see if I can find anything.

Cheers.
