Cooler Master MasterBox NR400 Case Review

System Build and Installation

Below is a list of the hardware included in this build:

  • MSI H310I Pro
  • Intel i5-8600K
  • Cooler Master Hyper 212 RGB Black Edition
  • 2 x 8GB Team Group Vulcan TUF Gaming Alliance DDR4
  • Gigabyte RTX2060 OC Pro
  • Corsair HX750i
  • LG 24x DVD Burner

Building in the NR400 was a breeze and even after my mITX build was complete, I had plenty of room to spare. I had no clearance issues with Cooler Master’s Hyper 212 cooler and had ample space for my full-length RTX 2060. Even though I decided on a complete air-cooled build I feel there is easily enough room for a full custom loop. Since I went with an mITX board I didn’t need to use the included grommets for the majority of my cables. The oversized processor cutout gave me enough space between the motherboard and cutout, which allowed me to neatly route cables to the motherboard and maintain an extremely clean build.

Moving to the back of the NR400, I also kept the cable management fairly clean with the available tie-downs. To help with the extra slack of the PSU cables, I removed the included HDD cage and chose to install an SSD below the motherboard cutout. The NR400 has 22mm of cable clearance between the motherboard tray and side panel so even with the extra SATA cables for the ODD, they had no trouble reattaching the panel.
