a "laptop" with a 5 cm high body would be a laughing stock pretty everywhere in the open, not to mention it would be a "laptop" you would have to carry a car battery with for a power supply, since no power management. judging by the photos there is no elegant and practicable way around it. it will always remain bulky diy chest. instead one could simply put it in a slim itx case or whatever it fits in and treat it as portable enough.
I also had the impression that this DIY project is rather on the niveau of the turning of the millenium. Of course it's difficult to make such a thing, but the gap between a professional product and this DIY laptop seems to be rather huge. Anyway, for the fun and hobby...
But a real solution would be easy: Simply support existig professional laptops (like MorphOS and AROS do).
