Hey there,
I have that exact same humidor cabinet. The top opens to reveal 6 to 7 bins and there are also 6 pull out drawers. The capacity is nice (if you really fit those 'gars into their respective places of rest). On my Trini humidor, there is a trap door in the back to accomodate a Cigar Oasis unit. I had to become creative and cut out a space inbetween the wall that creates the two drawer areas (left and right, where the doors are divided to be exact); this was needed to be done to facilitate the movement of humidified air around the complete humidor and not just on the side where the trap door is.
If you have any other questions, send me a PM ok?
Take care,
Darren
