Keep in mind that no computer can be made of 100% American parts. Computers are made of a diverse amount of components made in countries all over the world. In fact no computer can be 100% made in any country. Computers made in China are made up of foreign and American parts too. Hard drives, processors, RAM, motherboards and many other components are made throughout the world. Some individual components are made in factories in several different countries. Because of the diversity of the supplier chain, no computer is made of parts from just one country. But when you are buying an American computer, you are supporting American assembly jobs, and also providing a cost advantage for domestic suppliers of computer components.
