Nice cabinet.... the only thing you might want to consider is the drippings you will get when you unload some meat from the smoker. You are going to want something in the front to catch that stuff and be easy to clean.
My first thought is to get a plastic cutting board and lay it across the first drawer when you are ready to unload. And a sheet of cardboard inside on the cabinet floor would help too... or a sheet of plastic.
