Choosing a motherboard
When choosing a motherboard (also known as a mainboard), it's important to pay close attention to the motherboard's socket type, format, and chipset. These are the most crucial parameters, as they ensure the board's compatibility with the processor, expansion cards, and other components. The specific socket determines the choice of a suitable processor, while the remaining connectors dictate which other components you'll need for your future PC.Specifications
