You honestly don't need military grade equipment unless you're like, trying to run a desktop in the desert or space or somewhere with very harsh environmental conditions. Chances are you have your computer inside a building, in a case, and not strewn about the ground :p Its mostly a marketing ploy, because the only real difference between the regular components and "military grade" is that theyre tested at higher conditions than the regular consumer level components, but the differences between the two are slim to none.
My advice would be to thoroughly research the item in question that claims to be 'military grade' and find an equivalent motherboard with roughly the same specifications.
