Choosing the right motherboard (mobo) is a crucial step in building a custom PC. The motherboard is the backbone of your computer, and it determines which components you can use and how well your system will perform.
There are a few key factors to consider when choosing a motherboard. First, you need to decide what form factor you need. ATX is the most common form factor, but there are also micro ATX and mini ITX motherboards available. The form factor will determine the size of the motherboard and the number of expansion slots it has.
