So i need, a wireless router, and an external hardrive... Now here is my logic, each of those items will cost me between 60 and 100 dollars. And I've always been a huge fan of the G4 iMac. Does the airport in the G4 iMacs work like the one in my macbook, where you can hook it up to the ethernet cord, and then create a wifi network? I thought about doing this with a Mac Mini, but that would be too pricey.
