Ok... so here's my situation....I received an Apple TV for Xmas and I love it! I've been ripping my DVD's into my 500Gb external HD so I can watch it on the AppleTV. I just decided to put all my iTunes on the external drive. Now, I have other computers in the house that would want to listen to my music n watch the videos as well. I'm slowly running out of room with my external and I already have a 2nd external 500Gb used for Time Machine that has been maxed out already. Should I purchase a 1.6Ghz G5 PowerMac and use it as a Home Server? Would it be fast enough for all my Intel Macs in the house (5 C2D iMacs)? Do I need a server?
