The Antec Nine Hundred has a highly sophisticated quiet cooling system and allows a system to be easily customized. Gaming hardware produces significant amounts of heat, and Nine Hundred's design incorporates several cooling features, the most outstanding of which is the top-mounted 200mm TriCool fan with 3-speed control. Other cooling features include a perforated front bezel, three 120mm TriCool fans for HDD and system cooling, and two additional mounts for optional 120mm fans to cool graphic cards and the CPU. The large fans enable Nine Hundred to deliver quiet cooling to systems made up of even the highest end components. Furthermore, the power supply unit (PSU) mounts on the bottom of the case for improved thermal and Quiet Computing(tm) performance.
