Try sticking a couple S-100 chassis on a shelf of 1/2" plywood or supported with less than a 2x4 and unless you have additional support in the way of diagonal cross-members or extra support underneath the shelf it'll bow or break. Maybe not right away, but with time it'll start to sag. It saves much time to use steel brackets instead of cutting slots into the wood. I did my first shelf with the latter design and it took a long time, was kinda frustrating to get it together, and was not as sturdy as I would have wanted, but was still more than adequate. On my second attempt I used metal braces to support the cross members and found it to be much easier to erect and ever stronger than the other method. If I had to do it over I'd buy pre-fab shelves like the Gorilla racks.
