CPU Cabinet

Introduction : The CPU cabinet is made up of metal since it is lighter than any other materials such as wood. It comprises of many peripherals which are the most essential components of the computer. Hence it may also be verified as the Heart of the computer. All the connecting ports and slots are available only in this cabinet from which power is being passed from the power supply which is also available only in this cabinet.The Motherboard which is the brain of the computer is also placed inside the cabinet. Various other components that are available inside the cabinet are being discussed in the upcoming posts.

• Structure: The motherboard mounts into the case, and all the other internal components mount into either the motherboard or the case itself. The case must provide a solid structural framework for these components to ensure that everything fits together and works well.
• Protection: The case protects the inside of your system from the outside world, and vice-versa. Vice versa? Yes, although most people don't think about that. With a good case, the inside of your computer is protected from physical damage, foreign objects and electrical interference. Everything outside of your computer is protected from noise created by the components inside the box, and electrical interference as well. In particular, your system's power supply, due to how it works, generates a good deal of radio-frequency (RF) interference, which without a case could wreak havoc on other electronic devices nearby.

• Cooling: Components that run cool last longer and give much less trouble to their owner. Cooling problems don't announce themselves; you won't get a "System Cooling Error" on your screen, you'll get random-seeming lockups and glitches with various parts of your system. You'll also have peripherals and drives failing months or years before they do on your friend's computer, and you'll never even dream that poor cooling is the cause. Making sure that your system is cooled properly is one good way to save yourself time, trouble and money.

Note: A spacious, well laid-out case is a critical part of proper system cooling. Small cases require components to be packed close together, which worsens cooling in two ways. First, air flow through the case is reduced because it is blocked by the components. Second, the parts are closer together so there is less space for heat to radiate away from the devices that are generating it. This procedure has tips about how to properly lay out a new PC in the case.

• Organization and Expandability: The case is key to a physical system organization that makes sense. If you want to add a hard disk, CD-ROM, tape backup or other internal device to your PC, the case is where it goes. If your case is poorly designed or too small, your upgrade or expansion options will be limited.
• Aesthetics: The system case is what people see when they look at your computer. For some people this isn't important at all; for others it's essential that their machine look good, or at least fitsomewhat into their decor. In an office environment, PCs that all look different can give a work center a "hodge-podge" appearance that some consider unprofessional, for example.
• Status Display: The case contains lights that give the user information about what is going on inside the box (not a lot, but some). Some of these are built into the case and others are part of the devices that are mounted into the case.
