EATX PC boards represent the largest format of the standard ATX. This motherboard family is designed to provide more space and functionality.
The large size allows for board expansion and generally higher performance.
What are the advantages and disadvantages of EATX boards?
EATX boards offer high performance, but also cost significantly more than standard formats.
The huge amount of space available for memory installation and expansion ports means more GPUs, hence a better working experience; due to the larger size the components can be cooled more easily with fantastic overclocking.
