Motherboard

The motherboard connects all the other components to one another, and is the physical base upon which you build everything else. It contains a lot of your machine’s core features, like the number of USB ports, the number of expansion cards you can put in (such as video, sound, and Wi-Fi), and also partially determines how big your computer will be. Which motherboard you pick will depend on whether you build a low, medium, or high performance machine and how advanced of a user you are.
