If you have been using computers for a few decades, there is a good chance that you too have a few old desktop and laptop computers collecting dust in your house. They are too old to use and have little value, so selling them is not a worthwile endevour. You can't even give them to family members as even they find them lacking in power. Have you tried to use a 10 year old laptop with Windows 10? Not fun... Wouldn't it be nice if you could magically make the old hardware more powerful?
