Clean, modern lines with an all steel exterior: For those who want premium aesthetics, the 400Q has full steel front, side, and top panels for extra durability and gorgeous good looks. Quiet operation due to silenced side panels: Sound damping material placed on the front panel, side panels, and even the removable top panel quiets even the noisiest internal components. Compact design, full size capabilities: Don't let the compact dimensions of the 400Q fool you -- it can house a full ATX motherboard and multiple GPUs. Liquid cooling capable: With room for front, top, and rear radiators, you can choose to quiet down your GPU and CPU with liquid coolers just about wherever you want to. Direct Airflow Path: Drive cages are moved up and out of the path of cool air from the front intake fans and high-temperature components. Two AF series fans: Corsair-exclusive AF120L and AF140L fans efficiently draw ample cool air directly to your components without the turbulence that can cause fan hum. PSU and 3.5" Bay Cover: Clean up the inside of your case by placing cables and drives behind two modular, clean, and refined PSU and 3.5" bay covers.
