What is the best PC case for airflow?

Across the reviewers we read, mesh-fronted designs like the NZXT H7 Flow, Corsair Frame 4000D RS, and Fractal Meshify 2 Compact draw the strongest airflow praise. Specialist communities repeatedly describe the H7 Flow as flowing air 'like an open test bench,' and verified buyers echo low temps on the Corsair. Closed-front cases like the Fractal Define 7 XL trade airflow for silence and storage.
