You just need an airport card like one pictured above. About $20-$30 on e-Bay.
Your thread title "Can I upgrade a G4 Sawtooth to Wireless???"...was the question I was focusing on (how to make the computer wireless).
I was assuming that you currently had a wireless compatible router...otherwise...you will need a wireless router (any brand...doesn't have to have an Apple product).
Just be sure you get the card in Nicks picture and not the Airport Extreme. Just plain Airport card. Antennas are built into the Sawtooth's case. you will see the antenna cable when you plug in the card into the Front of the motherboard area.
Here is a pic with instructions out of the manual for that machine. Right click on Pic and click open in new Window for full size.
Thanks again for the info. Yes, I do have a wireless router that was supplied by my Internet provider. I looked on YouTube and OWC posted a video on installing the Airport cards. It even shows the antennae cable.
I just wanted to be sure I didnt need an Airport specific base/router or any other accessories/attachments. I picked up one on eBay for about $10.00.
