Hell yeah, this is awesome! It's almost the ultimate magicians home.
What I like:
1. Cool ass teleporters. (would have been nicer to have that feature earlier in the game)
2. Cool ass garden
3. That thing on the table increases your alchemy by 15.
4. The vault has guardians (now if I can get some guardians on the main level)
5. You get a skill book for alchemy
6. Atronarchs that don't run out of time! (of course, the whole point of them is to fill soul gems anyway)
On the storage situation, I just started dropping stuff in the main room along the walkway to the altars. It's kinda like window shopping everytime I go up there.

And the ring they give you stinks. It's no where near as good as the ring of wizardry and the ring of perfection.
