https://www.guru3d.com/news-story/cooler-master-announces-nr-series-chassis.html Cooler Master, an award-winning PC components company, today announces the release of the NR series with two new cases: The MasterBox NR400 and the MasterBox NR600. The smaller MasterBox NR400 supports up to mATX motherboards, while the larger MasterBox NR600 supports up to standard ATX motherboards.
Pricing & Availability The MasterBox NR400 and NR600 will be available for pre-sale today for a starting MSRP of $59.99 and $69.99, respectively. Availability will vary by region. For a good price I feel these two models are a worthwhile purchase.
