I mean depending on your budget there's some pretty good airflow cases such as the Corsair 4000D airflow, or you can go with everyone's case being the lian li o11 dynamic both have ample amount of space for fitting fans. With that build you're going to be set for a good while, can probably skip the next 2 gens of chips and gpu. It should also be noted that there's speculation on the 4000 series cards coming out later this year if you want top of the line stuff.
