Wineador size

I currently have a 12 bottle wine cooler I am using as a wineador. I just did a simple conversion I taped the drain plug added humidity beads and cigar boxes and a Tupperware tray. I am actually kinda disappointed in the amount of cigars I can put in it right now. I am going to purchase a larger one and do a full conversion with Spanish cedar trays and shelves. I am just having difficulty deciding on what size to purchase. I have been thinking of going with a 28 bottle but I have also been looking at larger ones. What I want to do is to make the top 3 or 4 levels shelves with trays for loose cigars, not for display just deep trays. I want the bottom half to be used primarily for storage in boxes. I cigar However sometimes I think forget box storage and just store everything in trays as I will probably be able to store way more cigars. How big of a wine cooler would I need to be able to store 400-500 cigars in trays then 5 to 10 boxes of cigars?
