Cooler Master HAF XB LAN Box / Open Air Chassis
The front he of the HAF XB uses a lot of plastic to frame the large mesh panel in the middle that sports the Cooler Master logo. With the I/O panel in the middle, that just leaves the two 5.25" bays on the left and the pair of 3.5" bays on the right, all of which open from the outside.
I moved in much closer to the front I/O panel so we can see what it has to offer. There is a large power button on the left that is backlit when powered and a smaller reset button above the activity LED for the storage drives. You then also get 3.5mm jacks for headphones and a microphone, as well as the pair of USB 3.0 ports.
The top of the chassis has a mesh panel to allow for the natural convection of air flow to just go right through the top. You also have the option to mount a 200mm fan here to aid in natural cooling, or flip it over and force a ton of cool air on the motherboard.
The left side offers a large handle at the top made of plastic that is inserted into the steel panel. Around and below it, you will find a large mesh area to allow air into the "first floor", but blocking off the "basement" level.
There is a lot going on in the back of the chassis. On the "first floor" you have a 120mm fan mounting position, some venting, the rear I/O area, and the seven ventilated expansion slots. In the "basement" you have the PSU on the left with the extension bracket and dual 800 fan mounting positions on the right.
The right side panel is a direct mirror image of the left side panel. It offers another large plastic handle for easier toting around, and again only ventilates the top half.
Under the chassis you find a few interesting things. There are large oval holes in the floor to allow for the inflow of fresh air, a dust filter under the PSU, nine wire tie points, and if you look really close, there are four screws to allow us to remove something.
