For the price difference... I could buy an ATX case! I don't really want an ATX case... but damn... $30 is $30! The mATX has DVI and HDMI on the port... but the ATX has a heftier (4 more cores) of whatever it takes to overclock better... I have old ATX cases already... just need new control panels USB 3... power etc... But by the time I bought those... Oh God... I really like this mATX case I found. Xion believe it or not... So... If there is a problem with this mATX, it's dead or whatever... I will have another option, I guess. :-\
