The cabinet top and bottom are each made of two separate pieces, held together not very well with slotted metal brackets. How hard would it have been to have cut these from a single sheet of material? It wouldn't have impacted the shipping weight or size. Also, the shelf arrangement is very peculiar and inefficient: it cries out for a 3rd shelf, at least, which fortunately I  was able to make from leftovers in my shop, but it could have been included at minimal cost.
