So... I had some lights and effects to the original mod. But that's not all.
A custom stair to acces to the first floor ( alchemy lab, arcane enchanter, bed, bookshelves are now here)
3 Mannequin ( 1 on ground level, 2 on first floor)
5 Weapon Plaque Displays ( 2 on ground level, 3 on first floor)
7 Weapon Racks ( 1 on ground level, 6 on first floor)
1 Dagger Display ( on ground level )
A custom forge
There is also some dwemer details to make the place a little more fulfilled.
You can also upgrade your YsCordelan version of your cube by changing the name of the files Dwemer Storage Cube.esp and Dwemer Storage Cube.bsa (not sure if it's work for the pre-stocked version), the pre-stocked version upgrade works, you just have to rename your .esp and .bsa to "Dwemer Storage Cube - Fully Stocked".
If you upgrade your mod and if using Ordinator perk mod, disassemble your upgraded crafting tables before installation.
V 1.04.1:
There is now 3 Weapon Plaque Displays and 2 Weapon and Shield Plaque Displays. Some models have changed too.
