Before You Buy

Before purchasing a compact case from this lineup, it is crucial to review component compatibility details that the product listings do not include or bundle by default. For instance, standalone cases like the NR200 and NR200P V2 require a compact SFX power supply measuring 130 millimeters or less; they do not accommodate standard, full-sized ATX power supplies, and no power supply is included in their packages. Similarly, Mini-ITX cases cannot physically fit standard Micro-ATX motherboards. You must verify that your motherboard matches the exact form factor specified in each listing, and remember that motherboards and internal connecting cables must be purchased independently.

Additionally, pay close attention to included fan counts versus total fan mounts. While models like the NR200 mention support for up to six fans and the Q300L V1 lists three fans with support for five, the listings do not specify the exact fan speed controller hubs or thermal performance benchmarks for specific room temperatures. If you are planning an air-cooled system in the NR200P V2, verify your CPU cooler height does not exceed 67 millimeters, whereas the standard NR200 accommodates up to 165 millimeters. Checking your part dimensions against the chassis clearances before ordering ensures a smooth, trouble-free building experience.
