I've been thinking maybe I should get a better case for air flow, my I have an i5 9600k with a regular air cooler & RTX 2070 super card. I have been looking at a Corsair 4000D case but maybe I should get one of these new bigger cases like the 5000D for future upgrades? I wont be buying a 40xx series card at the current prices but dont want to need to buy a new case the next time I do upgrade my system. Any advice would be appreciated as well as advice on what other fans I should look at getting.
