I feel pretty brazen for posting this having not lurked longer, but I didn't spot anything in here about this and I think others might be interested.
I have an 990fxa-ud3 sitting next to computer with a z77x-ud3h and it looks to me that I might be able to exchange the heatsinks on the VRM and south bridge.
This (AMD) board is going in for RMA, but I was thinking of buying a parts only gigabyte board off eBay and swapping those parts out to match my color scheme (black).
Does anyone have any similar experiences or advice? Known compatibilities?
