So I have a 20 inch iMac, love it to death. I have always wanted to just open her up and see whats inside, i have done it with MacBooks, iPods, Apple TV all that stuff but never attempted with my iMac, one because i don't know where to start. Behind the stand i think there is a lock for the back plastic panel but i am not sure, i would like some one to tell me how to go about opening this. A detailed description would be great, pictures would be even better if some one has already done this is, and has them handy. Thank You my mac lovin' friends.
