Yes! I was able to swap out the processor on my T7300 20" mid 2007 imac to an X7900 by following the instructions for replacing the heatsink here:
[guide|1017]
When the heatsink is removed, the CPU is exposed. Turn the slotted screw on the socket 180 degrees to release the CPU and install the X7900.
I do have a caveat: The connectors on the wifi and bluetooth antennas are extremely delicate and hard to get off/on. I just unscrewed the daughter boards, there is enough slack to leave them attached to the antennas.
After the install and reassembly, the computer booted up fine, there were no settings to make, firmware flashes or any other special procedures, just turn it on and bask in the glory that is the Core 2 Duo extreme.

+ Yeah, it runs just great. No heat issues or any glitches. The 64-bit geekbench score when from 2749 to 4239, an improvement of 54%. I also put a 4GB in one slot and a 2GB in the other for 6GB total RAM.
