;It can be confusing to set your budget for building a computer from scratch. You will have far more expenses than just purchasing the motherboard. You’ll also need to purchase a processor, a chipset, memory chips, and expansion cards. So before selecting the type of motherboard you want, make sure that all of the components you need will fit inside your total budget. There’s no point in buying a pricey motherboard if you can’t afford enough components to take advantage of it.
