Building a Custom Laptop to Your Specifications?

swordsaintzero asks: "I am not happy with the options presented to me in the laptop market. The system that comes closest, Alienware, costs more than my last car, and still doesn't have exactly what I need! Even Google didn't seem to come across any sites detailing anyone who had built a laptop from scratch. Does someone out there know of such a site? If not, does anyone know the motherboard brand being used in the Alienware Exteme series? If I can get some decent leads, I will post the ensuing mayhem, as I attempt to build my own."
