Nobody showing up again!
Ken, the Lang nucs usually have a bottom permanently attached and can be made from wood from the local stores. Screwing works well with butt joints, better than nailing. Yyou you can probably find plans on line and save a ton of money if you are so inclined. My guess is that you could build half a dozen or more for the price tag of one store bought nuc with freight. And get them quicker! KD 120 looks like a good nuc box.
