I guarantee none of you will ever buy ASUS again once you have to experience their abysmal RMA service.
How one company be so damn awful is beyond comprehension. Oh and even though they make motherboards for severe overclocking, if you remove the backplate to fit a cooler that will allow you to do the overclocking the board is designed for, it will void the warranty.
If you cover up the fact that you have removed it and are allowed to send it off, prepare for stupid shipping costs to the middle of nowhere and don't expect ever to see it or anything ever again.
