XClio's Windtunnel is engineered to support your high-performance gaming system in understated style! The exterior is designed around a pair of 250mm side fans, which direct fresh air onto your precious components. Both fans are controlled by a VR speed control. The fans' blue LED lights give the system a cool glow, let you see what's going on inside. With vents on the right side, top, and rear of the case, and mounts for an optional 80-120mm fan in the rear, your system stays cool, no matter how intense the action gets! An I/O panel mounted next to the front bezel hosts 2 USB 2.0 ports, AV jacks, and a FireWire connector for easy access, even with the front door closed. Installation of your components couldn't be easier, with XClio's tool-less clip and rail system. You'll have room for your Micro ATX or Standard ATX motherboard, five 5.25" external drives, two 3.5" external drives, six 3.5" internal drives, plus 7 expansion slots.
