The Cooler Master HAF XB EVO takes the famous High Air Flow series to a revolutionary new form factor with extreme cooling performance. The removable horizontal motherboard tray and large mesh top and front panels with two 120mm XtraFlo front fans create a powerful front to back airflow. There is plenty of space for even the tallest high performance tower heatsinks, thick liquid cooling radiators and up to 3 of the high-end graphics cards. The side panels with their rigid carry handles and the top mesh 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 SuperSpeed ports as well as 2 X-dock slots for lightning fast data transfers.
