That sounds like an excellent storage plan for a (backup) system containing sensitive data
it would not be entirely useless and indeed is an in-use option for secure backups. The entire computer is not kept in a vault, however removable storage that is fully encrypted, itself in a protective case (EMF & RF resistance along with physical protection), is then securely transported to such a vault and kept in such a scenario.
