Motherboard and CPU combo. X570 and 5900x

I've upgraded and no longer need the following: Asus X570 Gaming Plus AMD Ryzen R9 5900X (plus cooler) I'm including a DeepCool Assassin III cooler (cooler not pictured). We can also negotiate adding 16gb or 32gb of DDR memory if you need some. I have some pcie cards in other listing. Check them, consider making an offer.
