Tool Wall or Tool Cabinet?

For as long as I can remember I have been obsessed with hanging tool cabinets. I think it was probably seeing the Studley tool chest that started my obsession, but I am not sure. I have a design for a hanging tool cabinet that I plan on building in the future but until that time comes I wanted something that would suffice and was quick to build. I built this in approximately 2003 and to be honest it has served me so well who knows when I will build my tool cabinet.
