So I recently bought a mid case corsair carbide spec - 05 mid tower compatible with ATX, however as the title explains my board is also advertised as an ATX board but it is one inch wider than a full ATX board 12*9.6, what am I missing here? I checked on part picker and the compatibility was a match. Is there a range for ATX? Any explanations would be appreciated it.
Thank you.
Thank you.
