LCDs from older devices (DVD players, cheap picture frames, even off-brand tablets, as long as LCD has a ribbon connector) can be salvaged and used with any other device using a ~$15-20 LCD driver.
Some old digital cameras can be used as a webcam via USB.
Very old keyboards might have DIP chips that could be reused (if the rest of the keyboard is damaged and you’re into building your own keyboards that is)
