If you want to get the temperature of the case up to bake the smell out of it and kill any fungus/musty smell put the open case inside a vehicle that is sitting in the hot sun. It will kill the odor and you won't run the risk of the case getting wet in the event of a pop up rain storm. It can get pretty dang hot in a car. It may take a couple days but it will work. You might want to put a towel under the case to protect your interior if oil was spilled in the case, it might leach out.
