Have fun with it, try to read through rsavages "G4 for Dummies thread" . . . even if you aren't a dummy, it may provide some time saving hints. I'm not sure, but I don't think there is a "G5 for Dummies" thread, I think the G5 is in the same ballpark as the G4 . . . but from what I've seen people report here, there can be some stumbling with the G5 install???? Read first, cut once, or something like that.
