In addition to a couple Phillips screws, each side of the display assembly was held to the upper case with a 4 mm hex nut. Asus may try as they like, but with our 54-bit driver kit in hand, no fastener is secure for long.

For the record, the hex nuts weren't meant to be a deterrent to self-service, but rather a means of space saving. In addition to holding down the display assembly, the top of each hex nut was drilled and tapped to hold one of the motherboard screws.

The display assembly comes off pretty easily and we're left with the upper case that houses the backlit keyboard.

Just like the unibody MacBooks, the keyboard in the Zenbook cannot be removed from the upper case, which means the two must be replaced simultaneously.
