This storage system will hold the base game and the Sunken Treasures expansion while being able to hold premium sleeved cards. It does this by using the Sunken Treasures box to hold the boards and manuals. The boards are quite thick and I wanted to allow for other expansions - thus the decision to use the Sunken Treasures box to hold them. If, however, you plan on only holding one of the boards (and wish to use only the base game box) all of the compoenents and cards can fit into my existing version 1 copy of the storage system, located here. This storage system is composed of (10) inner trays. (6) of the trays hold player pieces (including player-start cards) that lay on top of rails. Cards are removed by pushing down on one end of the cards (seen in the picture) and hold player pieces underneath. There are additional player trays and room left in this insert for possible expansions.
