Warehouse Row - A switching layout

[Porthos63]

This one is going to be free standing. It needs to be a layout that I can take down and put away. If I was going to mount it to a wall I would use two french cleats, one at the top and one at the bottom. Each module is 4' long and 27" tall so my thought, at least right now, are four sets of independent legs maybe using some type of speaker stand.
