hi there
I currently have a Apple Powermac G5 Dual 1.8GZ
It has 150gb and 280gb hard drives
I need more space I'm running out
- so I want to ask - what's the largest size hard drive I can add? and what type of hard drive?
How many hard drives does the Powermac G5 take? (internal)

All G5s take SATA drives. There are two internal bays. The optical drive is PATA, and if you replace the cable, it is possible to put a 3rd HD (PATA) on top of the optical drive.
The max drive size you can fully use is 2 TB. This is a limitation of the Apple Partition Map which G5s use to boot from. You can install a 3 TB drive and partition it with GUID. It will mount as a data drive after bootup, but will not boot.

You may run into addressing issues with drives larger than 2TB... I don't know that the PPC OS X versions ever got support for LBA >32-bit.

Should be fine for a data drive. RAID volumes have gone past 2 TB for some time now without issue.

Software or hardware RAID? Software RAID means the OS is still dealing with devices <2TB.
