The hard drive trays are held in to the housing by latches which makes this step of accessing your drives a tool-less operation. In addition to the front bezel being constructed of mesh for ventilation, the two drive trays are also ventilated in order to make sure the fan draws air right across your drive.
There isn't much to the two hard drive trays. Patriot has included a support bracket to keep the side rails from getting bent during shipment. You must remove the bracket in order to install a hard drive. Keep the screws handy, as I tend to lose things like these tiny screws, and in this type of device having the correct screw is critical.
With the trays removed the interior connectors are easily visible. Nothing much to talk about, just a pair of typical SATA data and power connections. On the interior sides of the Corza are two slots for the hard drive rails to slide into. These slots will ensure the SATA connections on your hard drive will line up properly with the connections on the Corza.
