The reason I started this thread was that I have come across some very cool plexi custom builds from the PC side of things and was wondering how you'd do this with a mac.

Check out http://www.bit-tech.net/article/114/ to see what I mean.

The problem might be in acquiring the components, which for me isn't going to mean pulling them out of a working mac (why ruin it?). So it might mean hanging around like a vulture for a dead G3 or something that I can meld with another dead one(dead for different reasons obviously).

As for why bother? Because I can.
