Add a 4-port Super Speed USB (Universal Serial Bus) 3.0 Hub to the 3.5" front bay opening of a computer case. The 35BAYUSB3S4 3.5-inch Front Bay to 4-Port USB (Universal Serial Bus) 3.0 Panel Hub turns any available 3.5-inch computer case front bay into a 4-Port USB (Universal Serial Bus) 3.0 hub. Using only a single USB (Universal Serial Bus) connection, this front panel hub adds four easily accessible USB (Universal Serial Bus) ports to the front of your computer case through a 3.5-inch bay, or through a 5.25-inch bay using the optional Front Bay Bracket Adapter (BRACKETFDBK) accessory. Each of the added ports is compliant with the USB (Universal Serial Bus) 3.0 standard which supports up to 5 Gbps of bandwidth (10x faster than the USB (Universal Serial Bus) 2.0 standard) & up to 900m A of power. Accessorize with the PEXUSB3S11 PCI Express card to provide an internal USB (Universal Serial Bus) 3.0 port, so as to keep the external ports free for external devices.
