And i'm not sure about the mil tested case, but there is an aluminum and carbon fiber+poly carbinate option. At some point though, your going to have to buck up and realize that some of these options cost more, and either bite the bullet or lower your requirements.
I would like to have a laptop with 16 cores, 64G ram, 4K screen and a battery that lasts for a week and costs $200 too, but I have to compromise on the battery life and the price.
