A barebook computer (or barebone laptop) is an incomplete notebook pc. A barebone laptop is similar to a Barebone computer, but in a laptop form. It has only basic elements (case, motherboard, display, keyboard, mouse, etc.) and one has to add components such as CPU, memory, video card, hard drive, solid-state drive, WiFi card, etc. separately.
