Can a ATX board fit in a 12"x12"x12 case?

[Jack Clarke]

I was wondering about this because i am building a LANBox I wanted to know if this is true I am also using a corsair ax1200i power supply which is inside the case. so would i have space? I am also going CrossFire 2 way and liquid cooling.
So, Will i have space ?

A full size ATX board is 12" wide by 9.6" deep (305mm x 244mm).

Usually the specifications for a case includes which form factors it will have support for.

With what's going on inside such a compact case, I would advise you get a bigger one.
