Abstract: The invention provides a tool-less apparatus and method for attaching and removing computer devices and computer components in a storage cabinet. The bracket apparatus allows easy and secure attachment and removal of components in the cramped space of a storage cabinet without the need for saving extra space for maneuvering in the cabinet with tools. The bracket apparatus slides onto a support structure or frame track in a storage cabinet, locking firmly into place. A computer device or component can be slid onto the bracket and also locked securely into place. In addition, a spring release flap releases the computer device or component for removal or adjustment. A plunger release mechanism and fastener arms allow release of the bracket apparatus from the cabinet for removal or adjustment.
