The NZXT Bunker is a relatively simple device consisting of a black plastic frame, metal barrel type lock and key, and four port USB hub with extension cable. NZXT produces 20 different key combinations for reduced likelihood of another Bunker user being able to access your device with their key. Two keys are provided with the unit and there is a number ID stamped on each in case you need to replace a lost key or obtain an additional one.
Turning the key 90° counterclockwise releases the latch and the door springs open, revealing the four USB 2.0 ports behind it. The door has a mesh facing with a narrow slot along the bottom for the cable to pass through. This allows the door to be closed with the cable hanging out the bottom, while the larger head of the USB connector remains safely secured behind the panel.
Since the USB ports are recessed to allow for extra connector length, a simple spring lever action is used to slide the panel forward when the door is opened. Closing the door subsequently forces the panel to slide back into the housing. However as the progression of the movement is linear and does not begin until the door moves past roughly a 45° point, the clearance of the jack on the right-most side next to the hinge is reduced to only 0.86" or about half that of the others.
Let's get the NZXT Bunker installed and test out the operation.
