Accessories shown include: a fan controller, a DVD burner, and a USB memory card reader.Ĭases can come in many different sizes and shapes, which are usually determined by the form factor of the motherboard since it is physically the largest hardware component in most computers. In recent years, open frame or open air cases that are only partly enclosed (with freer ventilation and thus theoretically better cooling) have become available in the premium gaming PC market.Ī full tower case. The external case panels, at least one of which are removable, cover the chassis from the front, sides and top to shield the internal components from physical intrusion and dust collection, and are typically made from painted metallic and/or plastic material, while other materials such as mesh, tempered glass, acrylic, wood and even Lego bricks have appeared in many modern commercial or home-built cases. ![]() The structural frame ( chassis) of a case is usually constructed from rigid metals such as steel (often SECC - steel, electrogalvanized, cold-rolled, coil) and aluminium alloy, with hardpoints and through holes for mounting internal hardware, case fans/ coolers and for organizing cable management. The components housed inside the case (such as the CPU, motherboard, memory, mass storage devices, power supply unit and various expansion cards) are referred as the internal hardware, while hardware outside the case (typically cable-linked or plug-and-play devices such as the display, speakers, keyboard, mouse and USB flash drives) are known as peripherals.Ĭonventional computer cases are fully enclosed, with small holes (mostly in the back panel) that allow ventilation and cutout openings that provide access to plugs/sockets (back) and removable media drive bays (front). The power supply is on the bottom rear.Ī computer case, also known as a computer chassis, is the enclosure that contains most of the hardware of a personal computer. The motherboard (MicroATX) is in a horizontal position at the top, and the peripheral connectors go at the panel located at the rear of the case and USB ports at the top. Blow the dust out of the PC in the direction of the vacuum hose, so the vacuum can suck most of it right up.An ATX case. Run the vacuum and hold the hose near-but not touching-your PC. That said, a vacuum can come in handy if you’re dusting out your computer inside. It’s just a bad idea, so spare yourself the agony and pick up a compressed air can. This can create a static buildup and could potentially fry important electrical components on your motherboard, video card, and other places. We highly recommend not using a vacuum to clean dust off your computer components.

And if you’re worried about inhaling dust, you can always stop at your local hardware stop to pick up a cheap dust mask for less than $5. If you’re limited on space just be sure to keep a vacuum ( not for cleaning the inside of the computer more on that soon) nearby for a quick clean up afterwards.
