This machine was built for the sons (7 year old)very first computer. The H100i cooler from Corsair worked well in the case after some very minor mods. Flipped with the water ports to the back side of the case the hoses would touch the rear fan so flipped them to the front of the case and one of the front panel clips was in the way. Trimmed a 1/16 inch off the clip and a perfect fit with nice hose routing. Gave the board 4 stars due to it did not come ready for the 4th gen intel CPU. But with the USB Flash BIOS Update was able to get the issue resolved easy enough after about 2 hours of research and an hour on the phone with Asus. But finally found a youtube video to explain everything.
