Having only previously used Dell's Inspiron line of notebooks, I was pleasantly surprised at the build quality of the D520. Solid plastic casing encompasses the machine, the screen is attached to the base with sturdy steel hinges, and the entire machine is built around a magnesium-alloy frame. Slight flex was present when firm pressure was applied behind the screen, but I had to exert significantly more pressure to get any movement out of the palm rests, keypad or bottom housing. In the rare (hopefully nonexistent) case that the machine suffers from a drop, it is equipped with Dell's Strike Zone technology to protect the hard drive from short falls. Finally, any attempts to twist the screen proved fruitless as there was non flex.
