Cooler Master ships the HAF XB in a solid, fully colored cardboard box. Due to the unique dimensions of the chassis, the package is quite bulky, and there are two cutout handles to help you carry the box around. The front has an image of the chassis, while the rear goes into greater detail about the HAF XB's interior features. The smaller sides of the box hold another image and the specifications of the chassis.
Two thick Styrofoam spacers hold the case in place, while a plastic bag protects the unit from scratches and fingerprints.
You only get a small set of extras, although the chassis is quite large: the screws, some rails for hard drives, plenty of zip ties, and a manual. This is by no means a bad thing, as this is more than enough to fill the chassis up properly.
