These imac27 EMC 2309 and 2374 (Late 2009) are very similar; I wonder which parts are incompatible? I guess only the CPU, logic board and PSU?
Es esta una buena pregunta?

Only one thing! The CPU's!
This series was the transition between the Core2Duo to the newer Core 5 & Core7.

Does this mean that I could upgrade the CPU on EMC 2309 to Core 7, without changing anything else?
@tonyh2 - Yes, BUT! It needs to be 860 chip and Intel hasn't made the chip since ~2010 so its a bit of a crapshoot getting a good one if you can find it.
On the most part its not really worth the effort ;-{
Your skills on working on your system then gets into the mix, you could create a mess and then where would you be? There is just not enough performance gain in my mind.
