I have an iMac (late 2012), as you can see from the photos below the screen is shattered. The LCD panel is undamaged, but the glass is totaled. It is impossible to remove the glass without breaking the LCD panel, as they are merged or something. It is expensive to buy a new screen for these iMacs, and I don't even know if it would be worth the money and effort to repair the display. The machine works flawlessly. If you're wondering how this happened, the iMac fell from my desk and face-planted on the floor.
