This seems like a simple question.... I have a Power Mac G4 'Digital Audio' tower. From all the documentation I've seen, it's built to hold up to SIX drives. Apple shows them as two optical drives and four hard disks. I have only one optical (the Super Drive) and that will stay that way...Now, my question is: Can I put FIVE hard disks in it? It looks like the center HD space can physically hold a two drive carrier (like the one at the back/"right side") without interfering with the logic board, etc. That's what I want to do....will the machine support this config, or MUST it be four and two only?? I already have a two channel PCI card installed (and a total of three HD's running). Please advise... Thanx!!
