Hello! I have quite unique problem. My brother needs am3 cooler for his fx6300, but he does not have any kind of backplate or bracket on the motherboard. And it would be impossible to install new one, because the rear of the case can't be accessed. It is very old metal case and trust me, it can't be opened from behind. So I would love easy fix like cpu cooler that does not require any kind of backplate. Is there any cheap cooler that could be installed with similar mechanic to intel stock cooler, or something like that? Does not need to be anything fancy. Thx
