With the MasterBox NR200P MAX, Cooler Master is aiming to offer a complete package that allows the user to simply add their own components without having to compromise on cooling or power delivery. By including both a 280 mm AIO and whooping 850 W power supply, the NR200P MAX quite literally maxes out both bundled components.

With a pre-tariff, pre-tax price of $350, our estimation is that you will most likely see the MasterBox NR200 MAX retail for around $399 pre-tax. Considering the included V850 SFX power supply retails for around $150 and a 280 mm AIO can be had for as low as $100, the chassis is roughly priced at $150 including a PCIe 4.0 riser cable. In comparison, the classic NR200P sells for $80–90 on its own. This makes pricing of the NR200 MAX adequate, but not a steal by any means. However, it also does come neatly assembled, which is worth something. It will be interesting to see what Cooler Master will price the bare chassis at should they opt to sell it separately as well.

In terms of design, the Cooler Master MasterBox NR200P MAX manages to differentiate itself from what one may expect from an NR-series enclosure right off the bat with its smooth gray paint job. Ultimately, only the fine mesh top panel reminds us of the classic ATX and mATX enclosures.

On the interior, the MasterBox NR200P MAX is extremely easy to build in since you can take it apart completely, and it is only made easier by the fact that the AIO and PSU are nicely pre-routed as well. The chassis could even manage two 3.5" drives alongside long GPUs were it not for the overzealous branding attempt of the bulky PCIe riser cable, which turns out to be too short for some very realistic build scenarios. Luckily, you may simply buy yourself a longer, more flexible cable to solve that issue.

An interesting element is the enclosure's cooling capability. While we never expect an SFF ITX enclosure to do as well as a classic ATX variant when using our compact air-cooling, the bundled 280 mm AIO really shows how the NR200P MAX is intended to be used, with excellent temperatures and low noise levels. This interesting aspect shows when using the glass side panel. In such a setup, component cooling tends to work just a little harder, thus making the system ever so slightly louder. But looking at the results when blocking air access from the side, a bottom to top funnel is created, which pulls cool air across the NVMe SSD and chipset and results in even better numbers than with a vented panel. This is also due to the fact that the GPU is uniquely sandwiching the CPU and onboard components, while most ITX enclosures tend to stay clear of that type of setup.

Overall, the Cooler Master MasterBox NR200P MAX is a very good and somewhat unique entry into the flourishing compact case segment, but it has a few drawbacks.
