What I mean by cheap plastic is that the Dell Dimension I owned many many years ago snapped at the lcd bezel hinge after 10 days. It was returned and then snapped again at the battery near the heating vent and power plug. It was returned and then the side cracked when the CD Rom (I know I just dated the laptop) was ejected for the first time. That was returned and then I started having issues.

Cheap plastic is the same feeling you get when you run your hand over say a kids toy and then say against stronger plastics like that of a the plastics of a gun.
