Build quality? I bought the alienware 17, but sent it back to dell for build quality issues. The right touchpad button was loose. That was repaired by an engineer, only for the left touchpad button to begin sticking in it's depressed position. The USB ports on the unit were extremely stiff, not smooth at all, and required 2 handed operation at all times for fear of causing damage. Also, the newly supplied unit was not wrapped in plastic inside the box and consequently was (lightly) soiled with white dust from the factory environment.
