Here is our tv cabinet that I built. It is made from using merbau decking and 18mm ply. It 2000mm long, 500mm deep and 730mm high. I even made the legs by gluing a few pieces together, to make it solid. The top is 2 pieces of 18mm ply glued together. It's all been put together with some pocket hole screws. As an added feature, I ripped some decking down to some thin strip's and added them to the edge, just to hide the ply edge.
