No way would I refund. Too long after the sale and he already gave feedback. He obviously broke it himself - who in their right mind would leave feedback for something like a motherboard without testing it first
He's even more of an idiot for buying something like a motherboard when the seller states "no refunds"........I certainly wouldn't!
