For the record, that first picture looks like it's actually 3 separate, identical, units stacked on top of each other. Are you looking for that kind of flexibility or do you want a single large cabinet?
As for custom versus, "off the shelf", you can find something like you're looking for significantly cheaper than $1700 but you'll need to look for something not marketed toward collectors. Think filing cabinets and you'll find a lot more options at much cheaper prices in a whole range of material options. Or, you can go the custom route and probably spend anywhere from $500 on up, depending upon quality of build and materials.
