I'm looking to try and solve my storage and backup problems just now and was thinking that a G5 machine might be the answer. We have a dual 1.8GHz G5 tower sitting here doing nothing, so I was wondering if its possible to fit 4 new 1TB drives to it and get a RAID card? I notice that there's two HDD drive bays at the top, but is there any other way to expand the number of drives it can hold? I'll have a look on here to see if there's any RAID cards available for it, but if anyone knows, that would be a help too. Thanks! Edit: Would a card like this allow me to do software RAID 5 via Leopard? This machine is going to be used as a backup server, so speed isn't a major issue which I'm guessing would be the main advantage of going with a hardware RAID controller.
