This smaller guy is also on a cleat, screwed on two studs. The cleat is nothing more than a 3/4" hardwood piece which was ripped at an angle and then gang-planed to that angle. Behind the slanted surface (it is hinged at the top to open and reveal that space) are a #7 and some other smaller stuff, works well.
At some point it'll have drawers, before I die, promise.
