Verdict
Corsair Frame 4000D
7.5 / 10 Expert Rating
A smart idea for anyone who isn't sure whether they want mesh or glass yet, though it's a premium over the regular 4000D Airflow for the same base performance.
Phanteks P400A
7 / 10 Expert Rating
A dated but still capable budget mesh case; worth buying only if it's discounted below current-generation alternatives like the XT Pro.
