"Introducing the NZXT HUSH, a chassis designed from grounds up to be quiet while having ample cooling. Game and work without all the noise, thanks to the sound dampening foam that is used on the top, side, and bottom panels of the case. The HUSH is equipped with two 120mm fans running at low speeds while still achieving high levels of air flow. High-end gaming requires faster hard drives and power supplies, so we've installed rubber padding near fans and hard drives to further reduce the sound level. The HUSH also ships with USB 2.0, Firewire, and HD audio support. Benchmark Reviews proves that you can compute in peace, with the HUSH Classic Series Silent Computer Chassis."
