Computer Case

A Computer case is a enclosure for the components of a computer, usually meant for arranging, keeping components in place and protecting parts from water, damage, surges or other outside hazards to electronics. Usually constructed from steel, aluminum, cases varies in different sizes, components holdings (like a 5.25 inch or 2.5 inch bays), and brands. Plastic is used in some brands, or maybe even glass, wood. Some extreme custom builds have used homemade cases before. A case must be chosen specifically for not only the functionality of the user’s parts, but also be enough for future customization, as a case can be used over and over until a new motherboard size comes out, or the user prefers a different one.


A case is designed to hold multiple or a specific motherboard size, along on depending what it’s designed for, other components. A full ATX tower case usually are one of the largest cases available for the general market, and a medium ATX tower usually designed for most systems are used for a reasonable price, while allowing great customizability. Some cases designed for ITX or Micro-ITX motherboards are ‘flat’ rather than the modern-day traditional ‘tower’ cases.


Designed first by Intel in 1996, ATX has became a standard for all custom builders and decent-level computers. Usually, Medium-ATX cases are used, as ATX cases can fitfor multiple video cards, which requires proper airflow, component clearance for a proper build.

Micro ATX

Usually have fewer PCI-slots than Medium-ATX cases, some Micro-ATX cases can support small power supply units. Usually a popular choice for small form factors.


Usually in the form of flat case instead of the traditional tower case. Mini-ITX cases are used for small formed factors, and while minimizing even more from the Micro-ATX, it has become a choice for some builders.

Component Locations

A computer case supports the necessities of a computer, and some cases can support for more than usual (if the user is an enthusiast).

  • The motherboard is supported by stand off sockets screws (Some cases have mounts already). Usually there are holes on the case, and the builder has to line up each hole depending on where the holes are located on the motherboard.
  • PCI slot covers can be taken out, required for dedicated Video Cards. Sound Cards, Network Cards, and other PCI cards require empty slots for the case.
  • A large rectangular hole for the power supply, some cases conform small power supplies, or maybe even two standard power supplies.
  • Almost every case include drive bays, which could be 5.25” or 3.5”. Usually meant for Optical Bays, fan controllers, floppy drives, hot-swap hard drives and card readers.
  • All cases have a vent design (and mostly a fan). This can be anywhere, and any amount of fans can be installed depending on the case.
  • Bay holders for Hard Drives or Solid State Drives, can fit for 3.5” 2.5”
