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.

The two outer screws each drive a locking bar that engage tabs on the rear panel.
They definitely need to be unscrewed.

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

Please Note: If your iMac has an antenna for the airport extreme and not the bluetooth card. Don't buy the bluetooth get the airport extreme instead. Also, some newer devices may not work with these units.
