Once again, ICY DOCK has set the standard for hard drive enclosures. Introducing the MB876SK-B, an internal enclosure, and the first single drive bay mobile rack to feature our successful slim removable tray system. This drive sports an aluminum body for optimal cooling and maximum durability, fits all standard 5.25" desktop bays, and features a lock to keep your precious data safe and secure. To enhance its cooling efficiency, a 40mm warm air outtake fan is built into the rear of the unit to ensure that your drive will maintain an optimal temperature, thus increasing the life and dependability of the drive. The tray of MB876SK could be interchangeable with any of compatible systems, including the entire MB559 Series, the MB561 external multi-Bay, and our MB453/454/455 Series of internal multi-bay enclosures.
