Hi, I recently bought a 24" iMac 2.8 ghz. It will be replacing a Mac Mini G4 1.25 ghz with 512 ram and about 40 gig hard drive. Can this mac mini be reconfigured to be a backup with Time Machine or should I just use it as external storage? The mini also has bluetooth, I was thinking I could connect to it that way as well. I was thinking of networking via firewire but if the iMac only has one firewire port that might be a bit challenging.
