Description
The Cooler Master MasterBox NR200 redefines what is possible in the Small Form Factor (SFF) market by offering a premium, tool-free building experience in a compact 18.25-liter frame. Designed for enthusiasts who refuse to compromise on power, this chassis accommodates high-end hardware typically reserved for mid-tower cases, including triple-slot GPUs and 280mm radiators. Its modular design and 360-degree accessibility make it one of the most approachable ITX cases for both first-time SFF builders and seasoned veterans.
This product is for:
- SFF Enthusiasts: Users looking for a compact footprint without the thermal throttling often associated with small cases.
- Hardcore Gamers: Players requiring space for full-sized, triple-slot graphics cards up to 330mm in length.
- Content Creators: Professionals needing a powerful workstation that fits on a small desk while supporting multi-drive storage and liquid cooling.
- Custom Loop Builders: Hobbyists who want a chassis designed to accommodate D5/DDC pumps and multiple radiator mounting points.
- Minimalist Desk Setup Seekers: Users who appreciate clean aesthetics in black or white finishes that blend into modern workspaces.

Building in the NR200 is a departure from the cramped frustration of traditional ITX cases. Every external panel and frame component is secured with pins for easy, tool-free removal, allowing builders to access the interior from every angle. The internal layout is highly flexible; the side-mounted radiator bracket can swing out, and the PSU cage can be adjusted to accommodate different cable management needs. Whether you are air-cooling with a massive 155mm tower or opting for a 280mm AIO, the ventilated steel panels ensure consistent airflow to keep temperatures stable under heavy loads.
Compared to ultra-compact "sandwich" style cases, the NR200 offers significantly better CPU cooler height clearance and easier cable management due to its traditional layout. While it is slightly larger than sub-10L boutique cases, it provides vastly superior compatibility for off-the-shelf components like SFX-L power supplies and thick 3-slot GPUs. Unlike many budget ITX cases that use thin acrylic or plastic, the NR200 utilizes thick, powder-coated SGCC steel, providing a premium tactile feel and structural rigidity that rivals more expensive boutique options.
Q&A:
- Can the NR200 fit a standard ATX power supply? No, it natively supports SFX and SFX-L power supplies, though 3D-printable brackets for ATX PSUs are available from Cooler Master's website.
- Does this case support vertical GPU mounting? Yes, the NR200 features two vertical expansion slots, though a PCIe riser cable is required and sold separately.
- What is the maximum radiator size supported? You can install up to a 280mm radiator on the side bracket or a 240mm radiator on the bottom (recommended for custom loops with thin fans).
- Is the NR200 compatible with Mini-DTX motherboards? Yes, it supports Mini-DTX boards like the ASUS ROG Crosshair VIII Impact, provided the dimensions do not exceed 244 x 226mm.
- Are dust filters included? Yes, the case comes with magnetic dust filters for the top, bottom, and both side panels to maintain a clean interior.
