I already have a medium sized item sorting and storage system, using the common hopper filters method. Right now I have about 6 chests per item, and I'm wondering if there's a way to make the storage expandable without tearing things out.
I know about silos, but if I expand down, my final output chest moves down. If I expand up, I have to rip up the filter system and raise it as well.
Are there any good horizontal storage systems that are tileable, or ways of using a silo that lets you refill chests upward?
