Computers should be disposed of carefully when they have served their useful life, as some internal components can harm the environment. On the positive side, sell some of the components for cash. Regardless of how you scrap an old computer, do it safely and according to local laws regarding disposing of electronics. Recycle old computers, as they have components made of gold, silver, aluminium and steel. Reuse or recycle all of these parts, but note that some metals appear in specific components more than others do.
