Choosing a motherboard

When choosing a motherboard (or mainboard), it's important to pay particular attention to the motherboard's socket type, form factor, and chipset. These are among the most crucial parameters, ensuring the board's compatibility with the processor, expansion cards, and other components. The specific socket determines your choice of a suitable processor, while the remaining connectors dictate which other components you'll need for your future computer.
