I am rebuilding my pc. I am keeping my psu, and my gtx 1070 mini, I want to get a , AMD RYZEN 7 3800X 8-Core 3.9 GHz, and I want help with motherboard and case. I was thinking https://www.amazon.com/gp/product/B07FKTZC4M/ref=ox_sc_act_title_3?smid=ATVPDKIKX0DER&psc=1 for motherboard, but wasn't 100 percent sure. I also wasn't sure about a case. I would like to at most be 300 added between case and motherboard.
