This was too easy! All you need to do if you want to build one of these is buy 16" melamine shelving. All the front edges will already be finished with the edging tape and all you'll have to do is set the fence on your table saw to match the size of your container and you're all set just a couple straight cuts and you're done.
It will hold 60 sterlites. Perfect for neonate corns, kenyans, rosys, ATBs, maybe even balls for a month or so.
To save weight I didn't put a solide one piece melamine back on it. I just used two strips of thin panelling up the back in the center of two containers to act as a jam so you can't push them out the back.
For heat I attached exo-terra heat pads to the back with some tacs and staples.
Now all I need is about two more and I should be all set!
Thanks for looking,
Trevor
