I finally got around to building the custom shelving system I had model many months ago. It ended up being based around 6' tall pre-made sides from Menards home improvement center. I cut a third in half to make them 8' tall and added extra shelf supports. I ended up fitting 9 sets in all.

That helped a lot, but it's still pretty crowded in here!
