In mine, I do notice some water buildup from time to time at the base. Actually, my solution was to buy a few 1 inch plastic gliders that you put on the bottom of chairs and put those at the base of my largest (and cheapest) box. I ended up using the gliders for a few other cheap boxes as well near the fans to help with circulation, but again, my wineador has zero shelves and is packed full to the top with boxes.
I also put a bunch of those large 60 gram boveda packs in each box (because I'm paranoid) at my desired humidity level. So despite the fridge itself being capable of handling loose cigars, all of mine have their own micro-climate that I check every few weeks.
It really comes down to what works for you, and how much time/energy you want to spend on your setup!
