The first piece of hardware we are going to focus our attention on is the computer case. Obviously, it is what holds everything together in one secure space.

case parts

Above this is an image of an older computer case and tags describing each of the parts inside the case. It is important to understand the case because without basic understanding of the case it would be a lot harder to put together a computer.

A computer case has many names. I will list out the many names people refer to computer cases with. Feel free to share more in the comments.

Case Names

  • chassis (pronunciation is chas-ee, -is) which its definition is simply the construction forming the sides, top, and bottom of something, like a case.
  •  tower
  • system unit
  • base unit
  • Now the most obvious one, simply a case

No matter what you call the case its main job is to enclose most of the core components within a computer. There are a lot of different types of cases as well.

Rack – Mounted (19-inch rack)


Blade Server cases


These are just some examples of other cases out there.  Case form factors change dependent on the size of components you are going to be using inside the case, obviously. Take this picture for example.


If you were building a computer that uses a Micro-ATX board then you wouldn’t really need a huge case that can fit a Standard-ATX board, so you could save money and get a smaller form-factor case. That is how simple the case logic works. Of course it can get more complicated when different brands come into the picture because different brands make different kinds of cases. That takes us to our next topic.

Go here if you want more information on smaller – form factors, but I will mainly focus my attention on the Standard-ATX form-factor. It never hurts to learn more though.

The basic names for the different desktop computer case form factors would be Mini-towers, Mid-Towers(Which is the standard), and Full-towers.

For most Modern desktop computers you would usually go for an ATX case which would be the standard. You would only go larger or smaller for special or specific builds. You will learn more about these terms when we dive into motherboards.

Different Case Manufacturers

If you want further information on these specific manufacturers please refer to the Wikipedia links.

Well, that is the computer case everyone. I hope you learned something about computer cases. If you have anything to add or that you feel is missing please leave a respectful comment. Comments are 100% appreciated. Next we will dive inside the computer case!

Here is some extra information about the two most common form factors.

Form factors for desktop motherboards which greatly influence the case you would choose.

ATX – Advanced Technology Extended

  • micro-ATX
  • Flex ATX
  • EATX – Extended ATX – usually used with servers or large workstations

A computer case that fits a Standard-ATX board should be able to fit   all smaller ATX boards as well.

BTX – Balanced Technology Extended – these boards utilize newer heat and airflow technologies.

  • microBTX
  • picoBTX
