I bet the temperature to get magnesium to ignite is much higher than the devices would naturally produce or be exposed to. The only burning magnesium I've ever witnessed was either ground into a powder or in thin strips. It probably wouldn't burn so well in bulk. This was the first thing that popped into my mind on Monday, though. The original NeXT cubes were built out of magnesium, and after NeXT left the hardware business someone famously burned an old cube. If I recall correctly, it took quite a lot of effort to get it burning. The tale of the burning incident is here: http://simson.net/hacks/cubefire.html http://simson.net/hacks/cubefire.html As you know, years ago, when NeXT first contemplated making computers, Steve Jobs decided that machines should be in the shape of a cube, and that they should be built from cast magnesium. Although magnesium is a relatively expensive metal, it is remarkably strong and lightweight. No doubt, this let NeXT save on shipping expenses, although the added handling and manufacturing costs was one of the factors which led to the cube's high cost. At the time that NeXT brought their system to market, the only other company to incorporate a magnesium case was Grid, which was making a portable computer. (I am told that Apple also uses magnesium for the inside case of its Duo computers, but I haven't been able to verify this fact...
