Some of the pieces are so warped that the assembly screws are not long enough to work. One of the shelves had to be installed upside down or the back could not be installed; this means the pre-drilled holes are visible on the top of the shelf rather than hidden on the bottom. The shelves are not adjustable. One of the trim pieces cannot be installed because the top and side are so warped. It will have to be reshaped by hand to make it fit. Unfortunately this is on the most visible side of the case.
