Despite its size, the Raspberry Pi is a complete computer, one that can run desktop operating systems, including a trimmed-down version of Windows. With just the right peripherals, it can be used as a normal computer, and some have even turned the SBC into a laptop or even a desktop, complete with liquid cooling. These, however, don’t take full advantage of the Raspberry Pi’s small and portable size, a form that’s perfect for a handheld computer.
