I have larger racks of melamine, so things like weight pop out to me as it can become a concern the larger they are. If it is for heat and stopping, Iwould suggest a lighter material. For a small rack like this I am sure will make no difference, but when you get into larger melalmine racks, one panel can be significant.



On the subject of heat, if I may make a suggestion/observation: keep an eye on the temps in that bottom slot. I have had problems before with the bottom levels until I started raising on casters and insulating below the bottom level. This wasn't a problem when I built my first racks which sat close to the floor, but when Imoved them to a new locations, the floor was colder and called for a change in design on my racks. Hopefully you will not find this happening, but if you do it is a easy fix.
