A storage unit for use in a work environment includes a base assembly, a top assembly mounted upon the base assembly, and a vertical partition assembly installed between the base assembly and the top assembly dividing a space therebetween into a first section and a second section. The vertical partition assembly may provide a vertical passage so that utilities may be passed between the top assembly to the base assembly and between the first section and the second section. A fixed shelf assembly with an upper vertical partition assembly installed between the fixed shelf assembly and the top assembly may divide an upper space between the fixed shelf assembly and the top assembly into a first upper section and a second upper section. A lower vertical partition assembly is installed between the base and the fixed shelf assembly may divide a lower space between the base assembly and the fixed shelf assembly into a first lower section and a second lower section. A vertical passage may be provided by the top vertical partition assembly and the bottom vertical partition assembly (and through a shelf aperture in the fixed shelf assembly) so that utilities may be passed from the top assembly to the base assembly. The utilities may include any signal, such as voice, power or data. The storage unit may be provided with at least one exterior panel adapted for mounting between the base assembly and the top assembly.
