Verdict
Corsair 3000D Airflow
7.5 / 10 Expert Rating
A smart downgrade path from the 4000D Airflow when budget or desk space is tight, without losing the mesh-front airflow design.
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.
