Yuppers...open case spaces might look a little "unfashionable", but if YOU get a new idea with all of those "holes", you're primed to drop modules in to explore that idea! This, to me, is one of the big plusses of ANY modular system...and one of the biggest mistakes I repeatedly see right now revolves around people trying to make their case size a "final result". It won't work. Period.

Systems get bigger. It's a super-basic FACT. And one that new builders need to keep in mind....
