Not mentioned in my specs, but recommended, is the NZXT H2 "Silent" case. Intended for gamers, it has nine internal drive bays plus a hot slot on top, four front-panel USB ports (3x USB2, 1x USB3), and is designed for quiet running. With liquid cooling and a solid-state main drive it is extremely quiet and near ideal for studio use.
