This method of organization is the most flexible and cost effective method that I've found. If using the Plano 3700 you get up to 27 small compartments or 3 large compartments that are 13 3/8" long. If a Plano 3700 is used in each slot you'll have a total of 648 slots. You can also not use a storage container and directly store larger items such as sand paper, or shop manuals directly in the Storex Organizer.
