Near silent operation & prepared to take on powerful hardware, the Cooler Master Silencio is able to keep high-end setups running cool & quiet. Sound proofing on both side panels assist in vastly reducing noise levels. A sleek mirror finish front panel & clean lines present a minimalistic design aesthetic that speaks to its silent interior. The benefits of elegance & silence, combined with the functionality of built in Super Speed USB (Universal Serial Bus) 3.0, a multifunction SD card reader, & 3.5" X-dock HDD hotswap all make the Silencio a giant among its kind.
