Copied off one a few people here have made, but minus one shelf (for now.)
The cable in the back is that heat cable. I figured I would give that a try rather than wait on some flexwatt. So far it seems to be doing just fine. I still lack 9 tubs and the rest of my collection to be put in, but im buying that piece by piece.
