Computer Case Function

There are two main and basic functions for a computer case. Firstly it provides for a standard format for people to use to build their computers, and secondly it is there to protect your components and keep them cool. It is important to have a standardized case so that you can install different supplier’s components and know they will fit into your drive bays. The second important function of a computer case is to secure your components.

Keeping all of your components together in one place is also important. Here at HotRate, we found that cases will protect those delicate motherboards and other components keeping them dry and as dust free as possible. They also allow you to cool your computer more efficiently as they channel airflow through the computer to help prevent overheating which can seriously damage your components.

Sometimes the case and the power supply come together but not always and also, there could be more than one power supply form factor to consider.

When buying a case you must ensure that all three of these main elements match or you will run into trouble when building your computer. Today some of the most popular case from factors are the ATX and NLS as well as microATX/SFX which are starting to take over the market for the lower end systems.

It is important to remember that these cases are not interchangeable. They all have their own distinctive shape and they will accommodate different motherboards. Some cases are designed however to handle both the Baby AT and the ATX motherboards.
