I ended up picking up a wine cooler off of craigslist for a song and had Zebrawood faced drawers made by Forrest (wineadors.com) a few years ago. I also picked up the 6 piece tray set for my 70qt Coleman coolidor from him as well. I have a 150qt cooler that I'm still on the fence about getting shelves for to convert it, but I don't smoke cigars nearly as often as before. Here's some pics of the when I received the drawers for the wineador:
Sticker has been removed and I don't even have it plugged in now that it's in the basement, it stays between 65-70F year-round
The bottom drawer face covers the empty space on bottom. I keep a cedar box of my humidity "beads" (I use kitty litter) down there and there is still room for 1-2 boxes depending on how thick they are.
The ventilated back to help with circulation (at least that what I tell myself):
So any wine cooler will work as a humidor? I thought it was just a temperature chamber. When you pass the air across a cold coil it will lower the humidity in the box. So how are you going to maintain a higher humidity level?
