Here are some of my options, all things on casters for when I change my mind and decide to lay things out differently. Tall cabinet for storing tools and misc items, spray paint/finish storage rack, small parts bins for storing nuts, bolts, screws, etc. flip top cart for my planer and sander.
Saw blade storage on wall with dado stack and dowels to hold extra inserts.
Cart with my dust collector, Thein seperator, dust bin, used the space on the back for clap storage, have long clamps on a wall rack
Work bench with a lot of commonly used tool on the wall, this is a never ending project of making tool holders, next i have to decide if i want to build a cabinet or get a larger piece of plywood for the back
Hope this helps give you some ideas, also under the work bench is another cabinet with 6 drawers, 4 medium size and 2 large.
