NZXT H510 Flow @ TechPowerUp
 

The NZXT H510 Flow is based on the original H510, but offers a re-engineered front panel to solve the issue of airflow and thermal performance that was the Achilles heel of the original variant. Besides that, the case stays true to the same design and tooling, giving us a little blast from the past with hopes of remaining relevant today—two years later.
