Dreamfish, he of the 3rd ed army builder lists and remote gaming has put together an Indiegogo campaign for his modular gaming table design. The campaign is for the frame work that is both table and unique storage system for the modular boards. These you would need to supply yourself.
If you have the time and skill to make the boards, and the albeit small extra room to keep the storage racks I don't think a finer design is out there. Had I the time to make the boards I'd probably be all over this.
