A modular storage system and work station comprised of connectable modules that are operative to form portable work spaces that are easily adjustable and provide for an attachment system that allows for various accessories, computers, notebooks and the like to be detachably secured to the work station. In a preferred embodiment, the modules are comprised of a honeycomb-like structure that is operative to allow for the attachable interconnection of male- and female-type parts. The modular storage system and work station of the present invention may further be designed to be operatively transitional from a first carrying case-type configuration to a work station configuration, the latter defining a selectively adjustable work surface to which various accessories can be attached and selectively positioned. The storage system can also be scaled up to support larger equipment or serve as a display system with the help of electrical lighting elements, or scaled down to serve as more personal storage units such as a tool box or lunch box.
