The Simply NUC Rack Shelf helps turn NUCs into a server shelf. This full-metal rack shelf conforms to the standard 2U size and also fits a Telco rack. It is designed to fit comfortably between neighboring equipment and houses up to 3 standard-sized “H” or “K” chassis NUC units. The shelf, itself, is the metal casing, which houses the NUC units. The shelf chassis has spots designed to secure HDMI cables with panel screws.
