Here on the bottom we have the power supply mount area with vents. Both vents have a dust filter that is implemented on the outside of the case so removing them is a cinch.
Next seen is the PCB board for the hot swapping ability. They also provide power to case fans if needed. You’ll notice that out of 6 bays, only 4 use the hot swap board.
That’s because Azza included 2 adapters to mount SSD’s into the Hurrican 2000 and they probably wouldn’t reach the hot swap board to begin with since they were installed on the bottom two slots.
Here is a view of the other side of the PCB board to give an idea of what it looks like.
Here are the wire headers for the Azza Hurrican 2000. They are your typical motherboard headers with the HD Audio, e-Sata, USB 2.0 and, yes, even USB 3.0.
