When it comes to the relatively successful Raspberry Pi, this small and inexpensive computer is tiny enough to slide into any pocket, but it is far from being mobile enough for everyday portability. After all, this $35 computer does not come with its keyboard, display or battery, as you will need to provide those yourself. Fret not, why not print out all of the relevant parts? This is what the Pi-Top is all about, being a 3D-printable kit which would allow one to transform a Raspberry Pi Model B+ into a laptop, now how about that?
This particular kit will let you order a complete laptop kit which will hold a Raspberry Pi computer within, not to mention giving you the freedom of actually printing out (using a 3D printer, of course) several of the parts on your own.
