The Antec Nineteen Hundred - one of the biggest cases we have ever reviewed. The headline figures are mind-blowing; a dozen 3.5-inch drive bays, two 2.5-inch drive bays, three optical drive bays, six installed 120mm fans with mounts for two more fans, two power supply housings and nine expansion slots. If you want to install multiple graphics cards in your next gaming PC the Antec Nineteen Hundred sounds like it may be a contender.
