hey guys! i've got an old powermac g4 450dp lying around and decided i'd give it a shot and turn it into a server for my home as i need to create a backup solution from the files on my mac pro. i'd probaby add two more 500GB drives. my mac is specced at the present moment: powermac g4 450DP 1.25 GB sdram ati radeon 64MB video card 2 IDE hard drives, for 180GB total. i can replace these, if necessary, not a problem. i know there's an issue with my mac reading drives bigger than 120GB, so i need a PCI IDE controller to read bigger drives... i was thinking esata controller might be nice too, but i don't know if my machine is capable of handling the performance upgrade of esata anyways! now i have three questions with this. 1. all my "power plugs" for my IDE drives are all used up at the moment. when i add either controller (PCI IDE or a PCI ESATA) - do those "provide" extra plugs for my drives? i think the esata drives are in all-in-one cable (power and connector together), so would simply adding the card be good enough for the drives... what about the PCI IDE controller? do i need another card to get those power plugs to power up a IDE drive? just trying to think of the best and most cost effective solution to get some bigger drives into my machine. 2. also what would you guys recommend to use for backup? i was thinking of setting up time machine on my mac pro and then pointing the backup drives to the ones on my powermac g4. would that work? 3. and is mac os x leopard server necessary or over kill? thanks for any help!
