Verdict
Fractal Design Define 7
8.5 / 10 Expert Rating
One chassis that adapts between silent, storage-heavy, and airflow configurations.
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.
