When it comes to laptops, plastic exteriors are often a signal that the machine is lower end with as minimal of an internal frame as the manufacturer can get away with, which means that it’ll have extreme body flex which is bad for motherboard longevity. It also means that the laptop will probably squeak and creak when picked up and handled which subjectively feels cheap, and doesn’t bode well for the laptop being able to take a tumble. There are exceptions like the older ThinkPads which had robust frames under their plastic, but this is not typical.
