I thought about using the same thing as a box system. What I found about that type of office depot rack system is that the lids arent very secure. Well I guess to put it bluntly, their is no lid and a pritty decent crack along top where the snakes can get out.
I commend you for your efforts to find a cheaper rack system. They are quite the racket. I chose to build my own as well. If you have the basic hand saw and power drill it should'nt be too hard. When I built mine, I bought 4, 8 foot sheets of melamine which cost me a total of $100.00 at home depot. I then decided to perminently put it ontop of big industrial wheels for easy movement ( I totally recommend doing this , which cost a total of $30.00. Then I went ahead and installed my own heat tape. It also hols 12 of the 32 quart sterlite boxs.
After all was spent and done, I must have spent close to two hundred dollars on a shelf system that I can move around with no problem and can also heat the different shelves at different temps. If you bild it yourself you can take care of all your needs.
Home done is the best way to go if you have basic carpentry skills. Here is a picture of mine and I wish you luck at finding the cheaper rack system.
