Just bought an Apple iMac G5 1.8GHz 17" 160GB HD / 1GB Ram
I know I need to purchase an Airport Extreme card, has anyone got a particular site in mind with reasonable prices but trustworthy?
And will the card work with my BT Home Hub?

Also curious how i can use my old imac and really old powerbook g4 without the card, it seems like such a hassel getting one when older models work flawlessly without it?

Also where does the airport extreme card go in the imac?

Sorry for sounding like such a noob haha, would love it if somebody could explain it all to me

Thankyou guys!
