Looking at starting up some major printing in a few months and I'm looking to pick up a used G5 PowerMac with 4 gigs of ram and a few hard drive slots. I want to have hte hard drives set up in some sort of RAID array (all the files will be stored on here and don't really want a harddrive to crash and lose everything). The printer would be an Epson Stylus Pro 7800. The Epson website said it'll work fine with Tiger. Anyone ever used a G5 for professional printing?
