Actually, the exterior of some humidors isn't made to endure constant 70% humidity, the lining, glue and other materials might not like it in the long run. Plus there is no real use to put a wooden humidor into a wineador besides temp control and with 100ct humidors, all you have to do is put them in the room, closet or part of the house that is the coolest, usually the basement.
You could use those 100ct humidors in other ways. Keep them at different RH%, use one as a dry box, transition humidor etc.
But I have to say temp control is a b*tch, it was in the high 90s yesterday and I now know I will have to install an AC unit in my office because it reaches the high 80s since putting up walls and closing ceilings in the basement where my office and cigars are.
Use old boxes or Spanish cedar trays, maximize the use of space, you will need it sooner than later
