Just upgraded to a G5 dual. Looking for suggestions on what to do with my G4 Quicksilver. Is there much of a market for 2-year old Macs? Can I integrate it into a home theater system? If so, any suggestions on how would be much appreciated. Can I connect it to the home theater and then network it somehow with the G5 so I can view video files from the G5 on the TV? Any other advantages to using it in the home theater? Should I just use it for back up storage (if so, will both Macs talk to each other over Airport)? Any other creative suggestions? Thanks.
