Verdict
be quiet! Silent Base 802
8 / 10 Expert Rating
The pick when noise matters most, with an honest airflow tradeoff that high-TDP builds should take seriously.
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.
