I'm making a snake rack for my 41 qt containers. Do most people put a back panel on the shelves? would anyone advise against that? or what type of wood do you use for that? I think another sheet of melamine would make it alot heavier. Does anyone ever make their shelves short in the back, so there is room for wiring plus heat circulation? I was just wondering if anyone has tried that or if works good. I'm making the rack so it will be wide, not deep with one container per shelf and probably 8-10 high. Also is it better to wire in parellel, or is it okay to have each one with it's own plug so I can unplug the ones i'm not using..

Any help would be much appreciated. I have gone thru alot of other threads on building racks and these are just a few of my remaining questions. Oh wait I have another one lol, Is 5/8" melamine ok to use? Or should I go with something thicker? I can get 5/8 for free, since it's used in shipping to protect expensive sheets of wood and alot of the time thrown away. ;
