Hello Everyone, I just joined here. this looks like a great forum. I am looking at a Powermac G4 Dual 450 MHz with 1 GB of RAM and gigabit ethernet. I plan on using it for a file sever that 5 computer will use. It will be steaming video to the computers, sharing docs, and most importantly it will be used as the aperture library. It needs to be fast enough to do this or the whole app will run slow. If I finished maxing out the RAM and added a SATA card will it be enough?
