Hello I have bought a Antec Twelve Hundred V3 case. I am looking to put a specific Mobo in the case, but im not sure it will fit. The Case it's self is enormous and I was told that the Mobo I originally wanted could fit in it. Would a Asus Rampage IV Black Edition fit in the Twelve Hundred even though the Mobo is EATX and the Case is ATX? Originally I was told that it would, but I have been looking and I'm not sure. Any help would be greatly appreciated thanks!
