You cannot add Thunderbolt to any iMac that didn't come with one, at least as of today though probably also for the foreseeable future. There are no PCI slots in your iMac, and I've never seen a Firewire to Thunderbolt converter even proposed, and given the technology I doubt that one would be practical if even possible.

There actually is a mini pcie slot that the airport card resides in... and converting it to pci-e works. I was able to successfuly run a UAD-2 DSP solo card off of it.
My fear is that there will be no pci-e to thunderbolt.
