I got an Apple I-mac along with some other stuff last week. I took it apart and the board is blue on both sides. I found 3 things on the board that looked like "chips" One had a long metal arm over it, one had a heat sink on it and one was just on the board marked Nivda or something (assuming video card)
None came off like a regular PC. I've never taken apart an Mac so I just used the heat gun until the chips came off and threw em in my processor pile. Is that what you guys do???
