Quantum storage. It can store items in a file so if broken, the items will continue to exist in storage. Maybe a player set lock so only that player can break it? THough that would make it a bit more op. Item decay time without power can be a good thing to add so you have to keep it placed in order to keep your items from being deleted over time.
