I was going to share this piece of game room tip a while back but I think I forgot. This tote bin from Home Depot fits PERFECTLY underneath a pinball machine and it has wheels in the back for easy in and out. https://www.homedepot.com/p/IRIS-169-Qt-Store-It-All-Tote-Storage-Bin-in-Black-250084/300735810 (the black model is twice the price for some reason).

The only games in my collection it doesn't fit under is JM and the Gottlieb's. All older Bally/WMS, Stern (classic and new ones) and TNA. It's like it's made for it. Snug as a bug in a rug.

Snug AF

It nips the tote at the top. Somehow the game is having narrower legs. Same thing when I slide my harbor freight lift underneath, it's just about it gets in there.

Haven't really thought about that but the low frequencies that come from the bass just need a gap of air to escape.

Since I use all my 440sqft. in the garage for pinball, I don't have many storage options. It's mainly crap that usually goes in a garage that's stored in them. Some pinball stuff though.

It's epoxy, two coats + the concrete sealer done by a professional, it's indestructible but scratch easily. About $10/sqft.
