Bigger and badder than the rest, Antec's full-tower Twelve Hundred gaming case crushes the competition, with twelve drive bays, seven expansion slots and space for the largest graphics cards. The Twelve Hundred also fits both standard size power supplies as well as the CP Series, Antec's new form factor PSU exclusively designed for Antec cases. As every gamer knows, maximum cooling is a must, and the Twelve Hundred's got that covered with a top Big Boy 200 blue LED cooling fan, two rear blue LED 120mm fans, and three front blue LED 120mm fans! The Twelve Hundred also features a perforated front bezel with washable air filters, front USB, eSATA and HD audio ports for extra convenience.
