Buying/Building Shelves for NES Collection

[peachstapler]

I've close to completing my North American NES Collection (cartridge only) and I'm having a lot of trouble finding the right shelf to display the cartridges. I'd like to have the cartridge titles displayed vertically, 1-layer deep, so all the top labels are visible. Something like this:
(found it on GIS).

In my experience, I found it really hard on the games if I stacked the titles horizontally. Although it was easier to read the game titles, the front labels could accidentally become dented from the weight of neighboring carts and sliding them out/back into place.

Does anyone know of a retailer that has a nice shelf for sale? Maybe something online you picked up? There's probably nothing that is PERFECT for storing 800 Nintendo games, so maybe the solution is to build one? I'm also looking into that. Thanks for your suggestions in advance!
