CC_333 is correct - all G5's are OS X only. They'll run 10.2.7, the "For G5" version of 10.2.8, and anything else from 10.3 to 10.5.
As for what I'm going to use it for...at this point, Photoshop. I have an older version of Photoshop that'll do well on here, and I've never had a PowerPC thats really been as well suited for it as this baby.
As for the case - it looks great...until you try to carry it. Even just carrying it to the car, and then from the car to my apartment, was slow going. Those handles, combined with the weight of the G5 are like knives cutting through your skin.
