Very nice shelving, I was going to recommend something similar, but cabinet suggestions were ask for. From the photos, it looks like you knew what you were doing. I often build similar shelving, but use 1/2" OSB 2' deep and put the factory edge out. The work bench is cool, did you get the plans or design it your self?
