Ok so my mac mini (G4 1.25) has arrived free from a friend and i would like to clarify a few points as the web is full of confusion. 1. Latest os that can be run? 2. iTunes version to stream to Apple TV3? 3. Will that iTunes version run on 10.5? 4. As it only has 80GB HDD what would be the best way (and cheapest) to connect 2x 2TB SATA HDDs (1for the iTunes Library and the other for backup? Thanks for the advice. Hopefully you can help me get this up and running in my new office!!!!
