I have a 27" mid 2010 iMac. I also have a 17" imac G5. Should I sell the G5? I kind of use it as an external monitor at times, but can't think of any good uses for it right now. It's the 1.6ghz PPC G5 model and it has 768mb of RAM. Any good ideas? My 27" is so capable of doing everything that to use this thing as a server of any sort is crazy. I also have a 2004 powerbook with wifi that runs great, and has 1.25 GB of ram. I don't use it all - sell it?
