Thanks!
I did a fair bit of research on the Voltage Lab and came to the conclusion that I didn't really want the entire VRL system with their touch controller - just the module.
I definitely am considering leaving the moogs out of rack. Then I could do a smaller rack which would be nice. I'm also considering one of the moog skiffs and bolting it all together with those moog side panels. But one 60hp with the Pittsburgh doesn't leave much room.
I could possibly add a second empty moog 60hp and go 4 tiers. But in my closet like space two or three rows of 84 or 90HP would fit better. That's what kept pushing me towards a box of some sort.
