More than a year ago we took a close look at the original NZXT Tempest and gave it our OCIA.net Seal of Approval. Among the list of laudations were its good looks, roomy interior, massive amount of airflow yet quiet operation and reasonable price. Externally the Tempest EVO doesn’t look much different, it shares the same appearance, dimensions and weight as the Tempest. It also offers the same number of drive bays, cooling fans and expansion slots. So what, if anything, did NZXT actually do to the Tempest to warrant giving it a suffix?
