The armor only really would make senseif it was a giant aluminium heatsink with actual metal to metal contact to the chipset, regulators, etc... Which it doesn't seem to be since the chipset has its own heatsink already. All it does is obstruct airflow to the surface of the board, hindering cooling... But it does look nice. The backplate is the same kind that you see on some GPUs, it helps tremendously with heat distribution across the board in addition to additional structural stability.
