Recently purchased an MSI 1070 and it came with a 20$ rebate. I've used a rebate before but I don't remember how i went about it. Can I just take a picture of the UPC/Serial and send that in? I ask because I purchased this off Newegg and I know they won't accept RMA's once the original UPC/Serial is removed from the box. I'm not comfortable with hacking up my box and destroying my chances of an RMA.
