The side panel (or top) is held on by two screws along the rear edge. Removing it we find a surprisingly roomy interior, although I can imagine it filling up quick. There are two sets of snap-on rails to allow screwless installation of your optical drives in the 5¼" drive bays. Also found in the accessory bag are four stick-on rubber feet, which as I pointed out earlier are absolutely necessary for desktop orientations. A bag of miscellaneous hardware (screws, washers, standoffs, etc.) is included as well. The lower 3½" external drive bay and fan bracket must be accessed from the other side of the case. There is an additional internal 3½" bay positioned sideways just to the left of the 5¼" bays, and on the right side is the spot for the power supply, yes that's right it gets mounted in the front of the Duet.



The motherboard tray will accept standard as well as micro ATX size boards. The I/O plate is not a configuration I am familiar with however it easily snaps out and can be replaced with the plate that comes with your motherboard. Both rear 80mm fans have 4-pin power adapters with pass-through connectors. Front panel cables for USB and audio as well as connections for switches and LEDs have plenty of length to them and easily reach to even the bottom corner of the case. Additionally the USB/audio cables have both the standard 10-pin block header connector as well as having each wire broken out individually, although every modern motherboard I've seen adheres to the standard pin-out configuration for these headers. On either side of the case are grill openings with mounting holes for either 120mm or 80mm fans. NZXT also claims you can mount a standard 3½" hard drive in either of these spots in lieu of a fan, although I highly recommend installing a fan.
