Yes, you can use an ATX motherboard in an EATX case.
However, the reverse is not true – you cannot use an EATX motherboard in an ATX case.
EATX (extended ATX) motherboards are larger than ATX motherboards and have a different form factor.
They are designed to be used in cases that have the same form factor as EATX motherboards.
ATX motherboards are the most common type of motherboard and they are designed to be used in cases that have the same form factor as ATX motherboards.
Will An Atx Motherboard Fit In An Eatx Case?
Yes. an ATX motherboard will fit in an EATX case, but an EATX motherboard will not fit in an ATX case.
The main difference between the two types of motherboards is the size of the socket.
An ATX motherboard has a socket that is 305mm wide by 244mm deep, while an EATX motherboard has a socket that is 343mm wide by 332mm deep.
A narrower and shorter socket means that an ATX motherboard can fit into a wider range of chassis, while an EATX motherboard requires a chassis with more internal space to accommodate its larger socket.
Can You Forcefully Put An Atx Motherboard In An Eatx Case?
No, an ATX motherboard will not physically fit in an EATX case.
The mounting points for an ATX motherboard are too close together to line up with the screw holes on an EATX case.
In addition, the expansion slots on an ATX motherboard are also spaced too close together to line up with the expansion slots on an EATX case.
Will I Damage My Motherboard If I Use Atx Motherboard In Eatx Case?
Yes, you will damage your motherboard if you use an ATX motherboard in an EATX case.
The EATX form factor is larger than the ATX form factor, so an ATX motherboard won’t fit properly in an EATX case.
Furthermore, the screw holes and layout are different between the two form factors, so even if you could get the motherboard to fit in the case, it wouldn’t be securely attached and would likely come loose over time.
As a result, using an ATX motherboard in an EATX case would damage both the motherboard and the case.
