Full Tower E-ATX Computer Cases from Ebuyer.com

Extended ATX computer cases are, as the name suggests, larger than regular ATX cases. They are predominately used for gaming machines and for servers but can also be used for an everyday machine when a larger motherboard is desired.

As E-ATX cases are predominately used for gaming they tend to have eye catching designs. Built to impress these cases look great and many have extra features such as windowed side panels and LED cooling fans.

The difference between E-ATX and ATX

Although both are full sized tower cases there is a significant difference between the two. Whereas the standard ATX is a 12 x 9.6” form factor the E-ATX computer case has a larger 12 x 13 space for the motherboard. An E-ATX case will also have more expansion slots than the seven found on an ATX case.

Great cases from leading manufacturers

The increasing popularity of E-ATX computer cases means that all the leading manufacturers have developed their own cases. And here on Ebuyer.com we have stylish and feature laden cases from Coolermaster and Corsair as well as from other big name brands such as AeroCool.
