This article covers Cooler Master MasterBox NR200P V2 White Mini-ITXマザーボード・SFX-L電源対応 ミニタワー PCケース [ NR200PV2-WCNN-PSE ].

Overview

The Cooler Master MasterBox NR200P V2 White is a refined Mini-ITX tower case that packs enthusiast-grade expandability into a mere 18.25-liter chassis. Building on the original NR200P, the V2 introduces top-mounted radiator support for 240mm and 280mm AIO coolers, a feature that significantly expands cooling options for compact builds. Out of the box, you get both a tempered glass side panel and a steel panel with a new ventilation design, allowing you to choose between showing off your RGB internals or maximizing airflow. The included PCIe 4.0 riser cable enables vertical GPU mounting, and the bottom-mounted 120mm fan layout creates a vertical airflow path that keeps graphics cards running cool. Positioned as a mid-to-high-end SFF (Small Form Factor) case, the NR200P V2 targets users who want a powerful system in a small footprint without sacrificing support for large GPUs and liquid cooling.

Compatibility Guide

This case strictly supports Mini-ITX motherboards only. No ATX or Micro-ATX boards will fit. The power supply must be SFX or SFX-L format — standard ATX PSUs are not compatible. Plan your build accordingly. Graphics card clearance is generous: up to 356mm in length and 160mm in width. This means even flagship cards like the GeForce RTX 4090 (typically around 340mm) can be installed. The vertical GPU mount via the included PCIe 4.0 riser cable helps maintain airflow even with thick 3-slot coolers. Storage is limited to 2.5-inch drives (SSD/HDD). There are no 3.5-inch drive bays, so if you need large-capacity spinning disks, consider external enclosures or a NAS.

Product Info

Released in late 2024, the MasterBox NR200P V2 White carries a retail price of approximately ¥17,980 in Japan. It comes with a 2-year warranty through authorized Japanese distributors. Available in white (as reviewed) and black. In the market, this is a mid-to-high-end SFF case — its ability to host a 280mm radiator and a 356mm GPU in an 18.25L volume is exceptional for its size class.

Best Use Cases

  1. Compact Gaming Builds Ideal for gamers who want a high-end system in a small footprint. Pair a Mini-ITX motherboard, an SFX PSU, and a flagship GPU to create a powerful gaming rig that fits on a desk or in a bag. Not recommended for beginners who prefer spacious cases for easy cable management. 2. Water-Cooled Creative Workstations Content creators who need a quiet and cool CPU for rendering or video editing will appreciate the top-mounted 240/280mm AIO support. The ability to swap between tempered glass and steel panels lets you balance noise and aesthetics. 3. LAN Party Enthusiasts At 18.25L, this case is relatively portable. While it lacks a handle, it fits in most large backpacks. Be cautious when transporting with the vertical GPU mount — the riser cable is fixed, so vibrations could stress the slot. 4. Aesthetic-Focused Builders The white chassis with tempered glass panel looks stunning with RGB components. Magnetic dust filters and tool-less panel removal make maintenance easy.

Things to Consider

First, the Mini-ITX-only limitation means fewer motherboard choices and potentially higher costs. SFX/SFX-L PSUs are also more expensive and less available than ATX units, especially above 1000W. CPU cooler height is limited to 155mm, so large air coolers like the Noctua NH-D15 won't fit. For high-TDP CPUs, an AIO liquid cooler is the recommended route. Vertical GPU mounting can reduce airflow if the card is very thick (3+ slots). The steel panel's ventilation holes may be partially blocked; consider using the glass panel for better rear exhaust clearance. ## FAQ
Q: Can I use an ATX power supply in this case? A: No, only SFX and SFX-L PSUs are supported. ATX units will not fit. Q: What is the maximum GPU length supported? A: Up to 356mm in length and 160mm in width. Most modern high-end GPUs, including the RTX 4090, fit comfortably. Q: Is the case difficult to build in? A: It requires some patience, especially for cable routing and PSU installation. First-time SFF builders should allow extra time and refer to online build guides. The included manual is clear, but tight spaces can be challenging.
