This isn't really possible. There aren't many "standard" layouts for laptops like there are for desktops. A vendor pretty much deisgns a chassis, and gets components to fit. Hard drives, RAM, CPUs, some wireless cards: these are generally interchangeable. Everything else is system specific. The closest thing I can think of would be to buy a laptop, or take one you have laying around, dissasemble it, and build into a different chassis. Like a pizza box, or briefcase, or into Lego. Too many variables otherwise.
