I dont know if that would work. How would you heat each space? there is not a shelf between the drawers. I looked at that when I was thinking about switching to the rack system. You can buy the steralite tubs for about 5$ to 10$ a piece and put heat tape down and put them on the heat tape with a t stat and that would work. You can get one of the plastic shelving units to put them on or use counterspace you already have. I found a plastic shelving unit 3 shelves each shelf would hold 2 15 qt steralite latch tubs for for 20$. That is what I used before building my current rack system.
