This is an sutomatic storage room with 2 floors able to hold a load of redstone related items, and some other random items. If you want to change anything, just go behind the chests and open the hoppers which are pointing at the comparators. Put 41 of any item to replace the items already there and this item will now be auto sorted into that chest. The elevator can be called by both buttons and the input chest is at the top. Thanks :)
