My Mum bought herself a MacBook recently, and has given my old Mac Mini G4 back to me. I don't think it is worth putting on eBay, and it is too good not to use, so has anyone got any cool uses or seen any projects I could make use of this in?

It's not the version with built in IR (think first ever Mac Mini) and I have an AppleTV anyway. At the moment it's just sitting there, which seems a shame really.

Cheers

Cris.
