Nice cabinet. I priced those panels out from grainger and if I remember right they were kind of pricey. I also wondered how stable they would be with the longer bins like the 10" or 18" bins loaded up with nuts and bolts. We had a pre made cabinet like that at a place I worked at and it was pretty nice, had the panels inside and also on the doors. Was well built and held a lot but I think it was close to a grand for one cabinet.
