When I got my first Vino I just got some spanish cedar planks and made my own shelves. The second one I got was a package deal and had two MT Mouse drawers and one shelf. The first one has slowly lost all of the shelves and is not one big Tetris project. The other one has the two drawers on the top for singles and the shelf has two trays I bought for Duque Cigars. The bottom half is again just Tetris.
If you can get one of the guys to build you 2 drawers and one shelf I really think that will take care of most needs. You can just use the wire racks for stacking boxes.
