I'm working on the design for my first cab now, and I'm wondering what people have done for mounting cased CRT TVs in their cabinets. I've seen a few examples that create a full substructure out of 2x4s, and I'm thinking that will give me some extra lateral stability as well, but I've also seen other examples that don't put these in. For those that have built cabinets with TVs, what did you find that worked?
