It is the slower one, not the "extreme" speedy one, and is more rectangular than square in shape and does not have exposed contact blades. If you really want/need one, I have a few extra Airport Cards in stock and can sell you one for $20.00 (shipping included). I have personally tested each card with a GigaBitE G4 Tower PPC and will exchange if it doesn't work in your tower. You can download the program "MacTracker" from the internet. It will give you all sorts of information about all the Macs ever made. You should check it out. Ron
