Raspberry Pi 400: the $70 desktop PC - Raspberry Pi
Classic home computers – BBC Micros, ZX Spectrums, Commodore Amigas, and the rest – integrated the motherboard directly into the keyboard. No separate system unit and case; no keyboard cable. Just a computer, a power supply, a monitor cable, and (sometimes) a mouse.


Raspberry Pi 400: it’s a faster, cooler 4GB Raspberry Pi 4, integrated into a compact keyboard. Priced at just $70 for the computer on its own, or $100 for a ready-to-go kit,
Raspberry Pi 4, which we launched in June last year, is roughly forty times as powerful as the original Raspberry Pi, and offers an experience that is indistinguishable from a legacy PC for the majority of users.
