Just curious, would the Core X2 hold an ATX motherboard? I love the cube shape, but I don't want anything too big, so the motherboard I'm getting is the Sabertooth 990FX keyboard, and looking to use watercooling for the AMD 8370 processor, and either the 980ti or Titan X for the video card. Which out of the 2 would be good; the Core X2 or Core X5?
