The Cooler Master HAF XB takes the famous High Air Flow series to a revolutionary new form factor with extreme cooling performance. The removable horizontal mainboard tray and front panels with two 120mm front fans create a powerful front to back airflow. Despite its compact rugged design, there is plenty of space for even the tallest high performance tower heatsinks, thick watercooling radiators and up to 3 of the longest high end graphics cards. Within seconds the side panels with their rigid carry handles and the windowed top panel can be removed, transforming the HAF XB into a Test bench with direct access to the hardware. The front panel features two USB 3.0 super speed ports as well as 2 SSD compatible X-dock slots for lightning fast data transfers.

• Supports 240mm radiators with extra clearance for thick performance radiators or push-pull fan configurations.
• Supports Tower CPU coolers with a height of up to 180mm and up to 334mm long high end graphics cards.
• Motherboard Tray can be removed to install, remove or swap components.
• The first Case that quickly and easily transforms into a Testbench – Ideal for Enthusiasts and Overclockers.
• Dual USB 3.0 SuperSpeed ports and X-Dock slots at the front panel for lightning fast plug-n-play I/O.
• Rigid carry handles on the side panels.
