Cooling performance & overall design are partially objective and subjective. Sure, we had our in-house results and opinions (yes, we all love the beauty of this case) but we also wanted to test the NR through third-party proving grounds. We sent the NR Series cases to the biggest, most critical tech reviewers out there and here’s the feedback we received: “…you can’t go wrong with the NR400 or the NR600. Both offer great airflow and proved that they can handle the heat.” “…you can’t go wrong with the NR400 or the NR600. Both offer great airflow and proved that they can handle the heat.” – OverClockersClub  “We expected little from the MasterBox NR400 and it surprised us at every turn.”  “We expected little from the MasterBox NR400 and it surprised us at every turn.” – KitGuru Worth Buying Award “…the MasterBox NR600 is functional without being compromising, offering you plenty of air and liquid-cooling potential…” “…the MasterBox NR600 is functional without being compromising, offering you plenty of air and liquid-cooling potential…” – TechPowerUp Highly Recommended Award “There’s more room for hardware than meets the eye, despite this being a mini-tower. And the flexibility is just top notch… Good looks and good airflow? Yep!” “There’s more room for hardware than meets the eye, despite this being a mini-tower.

The case is sharp and subtle in its design without any of the gaudy options to drive price up.” “I love the versatility Cooler Master has included in this design.
