What store if any store do i need to go to to get the display cases and stuff? :swear:

Display cases? There are no display cases in the Anvil house. The Anvil house, Benirus Manor, has no upgrades to purchase. Once you finish the quest for it, that's it.

That svcks because i have a whole bunch of enchanted stuff but not enough space to show not even a quarter of it.

The Skingrad house is even bigger but far more expensive.

If you're on the PC, you could always download a house mod. There are tons designed to look pretty and to give players enough space to display all of their stuff.
