Want to build the E-ATX gaming PC of your dreams? Look no further as the Overclockers UK PC experts have compiled this ultimate guide on what goes into an E-ATX PC.
As part of our ‘Anatomy Of’ series, we’ll be focusing specifically on E-ATX gaming PCs, highlighting what components make up an E-ATX system, the pros and cons, along with our top hardware recommendations.
What is an E-ATX Gaming PC?
E-ATX stands for ‘Extended ATX’ and is the largest consumer form factor of PC. E-ATX gaming PCs typically utilise a motherboard that boasts an E-ATX form factor. However, these compatible cases can also accommodate boards in a range of different sizes, including Mini-ITX, Micro-ATX, and ATX.
Advantages and Disadvantages of an E-ATX Gaming PC?
Pros:
- Space for more complex configurations, such as water-cooling loops and multiple GPU layouts.
- Increased airflow – the additional space within the interior of the case allows for better natural airflow to help with cooling.
Cons:
- Often more expensive than any other form factor.
- Large form factor – not ideal for smaller office set-ups.
- Hard to transport – the large size of the case makes them heavy and difficult to move around.
