Build Quality & Assembly

The top/bottom part are made of a metal (aluminum?) coated with a plastic layer. There are a total of 8 tiny screws (4 on each side) to fix the top/bottom plate to the plastic middle part. Assembly is quite cumbersome due to the number and size of the screws. Half the screws did turn loose the first time they were tightened. The enclosure fits a normal size 2.5" 7.5mm hard disk. It is fixed to the PCB with two "normal size" screws.
