They are? I just replaced a hard drive on one of my client's 2007 Intel iMacs... Place the iMac face down on a table, loosen three captive screws, lift off the back and set it aside. Everything is easily accessed. Replacing the LCD screen or backlight would be more difficult... but everything else is modular.
That’s what I was talking about though. Give me an idea how much a replacement LCD screen for that iMac will cost? Let me guess it’s also going to be a proprietary LCD screen specifically for Apple?
