Airport card upgrade possible on my iMac to support handoff?!

Hi everyone!

I’m wondering if it’s possible to upgrade the airport card on this model of iMac to a new card to support handoff and continuity features such as the iCloud clipboard.

I’m fairly sure it’s possible, I’m more specifically looking for specific model numbers and parts and maybe even links to where I can purchase these.

I’m also planning to upgrade my graphics card and CPU and upgrade to an SSD. If anyone could also give any other information on these topics that would be great! (please do not attach the ifixit guide on the SSD upgrade, I have seen it :) )

The graphics card I have purchased is: Dell Precision M4800 NVIDIA Quadro K2100M 2GB Video Graphics Card N15P-Q3-A1

The CPU I have purchased is: Intel Core i7-2600K SR00C 3.40GHz Quad-Core LGA 1155 CPU Core Processor
