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.
The Pi-top kit will sport a 13.3” display at 1366 x 768 pixel resolution, where it is accompanied by a keyboard, a Wi-Fi antenna, as well as a battery which is capable of running anywhere from 6 all the way to 8 hours, depending on what you do with it. However, if you would like to be more unique, then you can always opt to customize the case as well as other components by placing an order for pre-made parts, or perhaps even obtain relevant designs to 3D print on your own.
