PC Case sizes

Venting
There should be enough venting in the system to enable well-directed airflow to cool the processer’s components. Power cable should be proximity close to component height.
Power Supply Mounting
There should be consideration for easy removal of the power supply.
USES OF THE ATX
Cooling the processor
The ATX has a fan that cools the processor .It is located in strategic location that position that facilitates the cooling of the processor when running operations. It is also designed to accommodate a
Power supply
ATX is designed to accommodate peripheral power connections that add up additional power to the CPU.


Other form factor
MicroAXT form factor
It was developed to adress the market trends and other technological issues. It is sometimes known as the uATX, it was developed in 1997
Board size
It measures maximum size of (244x244) mm while the small ones measure (171.45x171.45) mm
Its ports for mounting are a subset of a normal ATX. However, it uses same power connectors.
They have seven expansion slots as its maximum number unlike the full ATX boards.
AT form factor
Its board size is 13.8”x12”(351x305),this huge size cannot fit a modern mini desktop. Its size also means that there will be no space for drive bays thus making installation process for new drives difficult.

It has two identical power connectors that are made up of 6 –pin plugs. The power connectors are similar making it very hard for one to distinguish them. Majority of the users who have experienced this and are unable to differentiate them end up interchanging them, hence, destroying their boards. It is advisable that the two black wires should be adjacent to each other.
