Avon High School Tech Club 17 Motherboards • Motherboards are designed to work with specific CPUs, indicated by the type of socket that the processor fits into – For example: • Socket A, Socket 939, Socket 940 are designed for Athlon processors • Socket 478 and the new LGA socket 775 are for Intel CPUs. • Many resellers offer bundles consisting of a processor, a motherboard, and memory – These can be a good way to save some money, and make the selection and compatibility process easier Avon High School Tech Club 18 Computer Case • Hundreds of styles, shapes and sizes available • Look closely at the features • Some sweet PC cases are difficult to maneuver, or are cheaply built • Get the best case you can afford! • Look for "tool-less" case design, which enables you to click-open, click-closed • Most cases/motherboards use the ATX form factor, standardizing the sizes of the components and all of the power connections Avon High School Tech Club 19 Computer Case (cont) • It's critical that your motherboard match the form factor of your case • Look for helpful features like a removable motherboard tray, tool-less drive carriers (where the hard drives are installed), and multiple fan locations for cooling the system (cooling can be one of the most critical features to ensure the long term health of your PC) Avon High School Tech Club 20 Computer Case Tips • • • • Get more case than you need Make certain all your components fit in the case Consider cable management (space) RESEARCH!
