The XBOX 360 (original model) has a 3.0GHz tri-core PPC processor and some nice video card. It would be interesting to try and use it as a very fast PC. Since it is PPC, it seems like you'd be able to run Leopard on it. I'm assuming you can't just swap the hard drives and go. Are there any hacks out there for this? I couldn't find anything on Google. I happen to have a semi-broken XBOX 360 that my brother's friend gave him.
