1. I wouldn't recommend even opening up your iMac unless you're adventurous and confident in doing so.
2. You might be better off using this. You might find a cheaper one that uses compatible drivers.
 
Not an official Apple Card. The Apple cards that work in the G5 are the G model AirPort Extreme (the $30 one on Apple's Website), plus, you cannot buy an N card separately.

i can't remember if the card is built onto the MB or not even, it might be, so it might not be removable to replace.

I looked online to get my answer, and the G5's the card was removable. I don't know about the new ones, but Apple only sells the G model on their stores.

The Airport Extreme (PowerPC) was a larger Mini-PCI card. The newer Airport Extreme (Intel) card is a smaller Mini-PCI-Express x1 card. You can get the MacBook card and install it in an Intel mini to give it 802.11n support.

Good to know. But that still doesn't give the OP N from an internal card for his iMac.

I would almost suggest using an Airport Express to connect to an N network, then use an Ethernet cable to connect it, as USB does have some Bandwidth issues.
