Okay, so I've pretty much gotten back into collecting old consoles and games (mainly stuff I sold the first time around) and find that some cheap wall shelves will reduce the clutter of cartridges, game cases, etc.
I'm basically trying to do this with a very small budget. I was buying some 8" deep boards but I didn't like the options for supporting the planks that were available (too fancy, too bulky, too pricey, etc.) My though then, was to secure 2x2's to the studs and then screw the shelves onto these supports (see picture below). I figure all shelves below the topmost would have 6 inches of usable space (all that's needed for most - if not all the cartridges, boxes, jewel cases, DVD cases, etc.).
My question is if this would be secure enough for my purposes. I'm not figuring all this stuff would be terribly heavy. Again, I'm trying to keep it simple and cheap but effective and moderately handsome. Any thoughts/advice/input would be appreciated.
