I've had two 2133 20' iMac's and both had a removable CPU. I replaced the 2,0 Ghz processor of one of them by a 2,4Ghz (coming from a 24" defective logic board) and it runs perfectly well. It shows up in the system info part as a 2,4 Ghz Intel Core 2 Duo. So have a look under the bonnet to see if it's removable !
