Inside the NZXT H2 Mid Tower Case
Starting with the front of the chassis, I removed the front bezel and spun it around to see what all is going on. When I did, the pair of 120mm intake fans comes right out with no wiring involved. The wiring stays connected to the middle of the bezel and with use of contact points the fans get powered up.
The wiring is tied together from the front and the rear. The USB 3.0 cable acts as a tie point for the loose ends from the front I/O. the hardware and instructions can be found in the thin white box sitting on the outside of the hard drive rack.
While the top three, 5.25" bays have tool-free latches, and the eight hard drive bays have slide in trays, the entire left side of the bays are covered in thumb screws. If you want to lock the optical drives or the hard drive trays in place you use these thumb screws to do so.
Around the outside of the motherboard tray there are seven holes for wire management, three of which have rubber inserts to make things look better. With compatibility for baby-AT, m-ATX, and ATX motherboards, and up to twenty places to tie wiring to, you should be left with a very clean build.
At the back you can see the outside rail is cut away to allow access to the seven expansion slots and the thumb screws. The third fan included in the chassis is this 120mm exhaust fan, and NZXT offers holes for routing water cooling tubes through the back as well.
Behind the tray you will find up to 25mm of clearance to route your cabling in. The USB 3.0 cable and front I/O wiring comes pre-grouped, routed and attached to the chassis out of the box. For each build it may require you to remove these wires to make it easier to route them to your components.
The wiring is all black aside from the tell tale blue USB 3.0 cable at the top. You will find four fan, 3-pin power connections and a Molex power adapter that hang higher on the back of the chassis. Shown is the SATA cable from the HDD dock, Audio, USB 2.0, and motherboard power and LED connections.
