ok so to start of im new to building a pc from scratch and while trying to put in a liquid cooling system i realised even though there was a place to put a 240mm radiator at the top but there wasnt enough clearance thanks to the asus maximus viii hero but even if that i/o shield wasnt there it would still block a lot of important things so i was going to take it out and replace the case only to ralise i had used the wrong screws and had used the ones to hold the power supply in so i believe i have stripped the standoffs since when i turn it after a certain turn it falls back down. i was wondering if i can fix this anyway i have tried getting in contact with asus but there online chat isnt working and neither is there system to register a product for warranty.
