Magnesium alloy is reasonably common in notebooks and other consumer electronics. Sometimes it's an internal structural element with a different cosmetic outer part, and sometimes as in the Framework Laptop 16 along with some of the higher end ThinkPads, it's directly the outer shell. As noted in the linked story, it's actually really difficult to burn the kinds of magnesium alloy that are used for structural purposes, and the author had to jump through hoops to get it to work.
