So I finally found a use for my loyal G5. Besides being used as a normal machine, I tossed Leopard server on it and it's now backing up every single Mac i own that's running OS X and connected to the network. As of writing, I have 7 machines being backed up all at the same time.
Honestly, I think I broke a record for having something like this going on right now. LOL
It's my TiBook, iMac, MacBook, MacBook Pro (not pictured), the G5 itself, 12in PowerBook, and 17in PowerBook all at once.
