The various aspects of the present invention are directed to moving carts and moving cart assemblies. One embodiment comprises a moving cart assembly with a plurality of interlocking, vertically stackable, storage modules. The modules of this embodiment comprise a frame, preferably having at least four sides, e.g., a top, a back, a right side and a left side. Each module also comprises something to enclose the interior space, such as a pair of doors or a drawer which is selectively slidable into the frame. The needs of a particular office can be readily accommodated by using greater or fewer numbers of drawer modules and/or cabinet-type modules.
