Enable the console with ~ then enter the code "player.coctestinghall".You'll be teleported in a room with hundreds of doors. The main doors are The Armour and Weapons Rooms. They contain every weapon and armour in the game!!! Including Umbra, the Imperial Dragon Armour, Daedric Statue gifts and others!!
Enjoy...
