Locutus' cube

According to the role playing game Star Trek Adventures - Core Rulebook, this cube was called Cube 632.

In the Doctor Who crossover comic Assimilation², the Eleventh Doctor and his companions Amy Pond and Rory Williams travel back in time to the Battle of Wolf 359 to recover a copy of the Borg central archive from Locutus' cube during the battle after the present version is deleted by the Doctor's enemies, the Cybermen. On board the cube, they encounter Captain Picard assimilated into the Borg Collective as Locutus, but he ignores them as they proceed through the Borg ship to a computer terminal where the Doctor copies the executive libraries, as Locutus, like all Borg, doesn't register them as a threat so long as they do nothing threatening to the ship.
