Well I've already ordered a G3-XE as I'm not convinced that the G4 will give enough "bang-for-the-buck" performance increase, but I figure that if I'm wrong or an even faster G4 comes out then I'll be able to upgrade my existing XE board.
I also ordered it in a nice case with 4 x 5.25" bays, 2 x 3.5" bays, front mounted USB ports and a 300w PSU.
I've been impressed by cheap, low-end ATI Radion cards in my PC's so a 7000 or 7500 Radion should be enough to keep me happy.
