Thank you for looking I have a friends iMac that I have worked on before. As you will see I have never replaced a logic board. I see that mac's are very specific on this. I did a lot of reading, at least I thought so. Everything seems to match up on the numbers, but its doesn't have the slot area or the temp sensor that I circled. Now I dont mind doing some soldering, but I think I just wasnt smart enough to read everything.... Would anyone care to chime in, and let me know what one I should have got? Thanks for any help.
