My iMac has only ONE catch, the central one, so the two outer screws are not to be touched.

In fact, I tried so hard to unscrew them, with a good screwdriver, that my hand hurt. Knowing that some times captive things (like these screws or a faucet) can be already at the end of their travel and we only lock them further into that position, I tried both screwing and unscrewing to no avail.

Looks like one of these screws is not like the others... a security Philips?! Never seen one of those before.
