The card in the latest 2011 iMacs just released is the Atheros AR9380 model XB112 (power transmitter) this has a 3 channel out put i.e. you need a pci express to pcie mini card adapter with 3 aerials). The potential result is my friends iMac gets a connection speed of 450Mbps although on mine I am getting 270Mbps > however its currently running at 2.4Gps + mode not full dual channel (5gps + 2.4Gps). You also require a recent model airport extreme base station to use full simultaneous bands. I paid $50 for the genuine iMac card from the states and verified it against the card shown in the ifixit iMac teardown. The older dual channel card also works fine (the one in the link in an earlier posting) and goes for about $20. The pci adapter was less than $10 posted from HK.
With the assembly the adapter to card mounting you need 2.5mm screws, try an electronics shop, metal is best as they form part of the founding circuit. Put the head of the screw on the aerial lead socket side and a nut as a spacer between both cards - otherwise tightening the cards together will strain the mini pci express plug. Then when you install the aerial leads VERY carefully align the plugs making absolutely sure they are in the correct position then a firm push to click the plug into place. Take your time as if you damage the tiny plug the card is stuffed. Refer to the Appleinsider article "Mac OS X 10.7 Lion to support 450 Mbps..." article for full configuration details.
