Looks great. I agree with imalizard that wouldn't it need some ventilation, looks a bit stuffy in there

? Should be easy enough to fix. The part that would slow me down would be the glass front, which presumably would have to be cut professionally?
Do you propose using a cord or mat to heat it?
How flat does it sit: does the alum frame at the front tilt it up at the front or is the bottom part of the frame flush with the base of the container?
