I used to have an old PC that I used as a network server in a mixed PC/Mac environment. I used it as a print/network server to do simple backup, keep all my music, and do some back up jobs for my PC. It just finally crapped out, motherboard is bad but the hard drives are good. I could easily drop them into an enclosure. I was considering alternatives and just saw the apple airdisk. I have external drives for both the PC and MacBooks. I have two questions: I have an old Airport Extreme 802.11g - does it support AirDisk? If not, is it work upgrading? What are other suggestions for creating a networked hard drive that don't involve buying a brand new computer?
