If you click on the first picture of the case with the electronics removed, you can see the hard point/mounting points in the corners. The PCB board, screen and light guide are all attached to a pot metal frame. Four screws secure the metal frame to the case at the corner hard points.
The case forms the back of the device and is what the electronics fits into. The Bezel is the part that snaps into the case and forms the "top" with a big hole in the middle to view the screen. There is no bottom lid, the bottom part is the case bottom and four sides.
If you look closely at the Bezel insides shown on the right above, you should see the tape.
