This thing is SO tempting. Would basically need nothing IMO, but 60mm CPU fans up at the top blowing right to left and inside the ice box itself blowing up would promote wonderful circulation I'm thinking.... Each side is 14x14" square and ought to handle two dress boxes side by side easily. Metal shelves already in place would not hinder air circulation. I have an unused LeVeil humidification unit that ought to be ideal for this box and I don't believe I would even have to drill any holes to get power inside. A wire should easily fit up through the ice box water drain hole.... Doors seal quite well already, but maybe a foam weatherstrip would be a benefit.
Someone (besides my wife) tell me it's a bad idea please.....
