My motherboard is an Msi B450 Gaming Pro Carbon AC and I am not sure what case to get, I want good RGB in it, and good airflow, my budget is about 80 bucks 10 euros less or more, and I live in france, next to switzerland though so I can also use german websites. I was thinking and looking between Deepcool Matrexx 55 (3 fans included) or Corsair Spec-Delta RGB or even a budget case and then I can buy RGB fans to add on later, I don't know, please help.
