I built a three tier Moog like this. The red frame is from a guy on Etsy that 3D prints them and it wasn't expensive.

Very sturdy and nicer than I had hoped. He prints them in colors other than red.
Really good work. Currently just $75. Can't beat that.

I kept the wood end cheeks but you don't have to. I thought they would end up lost in a drawer so I kept them on.
(To do that, I had to get 24 longer screws than what came with the frame.)

For the top row, I used the very nice empty Moog case that they used to sell.
They don't make them anymore, so you'll have to hunt around, but they're out there. A perfect match.
Unlike the other two, that empty case doesn't have it's own power so I used a Behringer PS,
running it all with one (big-enough) wall wart with a 3-way splitter wire to power the whole thing.

I did end up swapping rows 1 and 3 to keep the wires out of the way of those nice Subharmonicon knobs.
Worked way better on top. Here's how it ended up, as "The Squealer" (that really needs some mults).

For me, patch cable spaghetti never gets that bad.
I get lost on discovery road and forget what I'm doing, way before I run out of jacks and the wires to connect them :)
