The small cases are my favorite. The previous one (I took it to work now) was the SGPC K55 6-liter. The NR200P is a very high-quality case. Its materials are sturdy, it has scratches for cable management, it has metal side panels with holes and a transparent window in the packaging, a riser cable, two rubber feet for a mechanical disk, and all the cables needed for assembly. All small cases are overpriced, and similarly sized cases with thermal performance cost around 200 euros, while this one, at 50 euros, is the best in terms of performance/price. If you like small cases and want quality beyond the low price, this is the ideal case. My machine runs on an Asrock B450 ITX, Ryzen 5600g, RTX 3060, 16GB 3200Mhz RAM, Thermaltake SFX 450W PSU, Arctic Freezer II 240 AIO, and the temperatures are very low (I will provide values when I do the stress test). It is quiet, only at night when there is absolute silence, a minimal sound can be heard. If I turn off the two top fans or replace them with better ones, it will not be audible at all. In the photo, I have it next to the old one before I start the assembly, where I transferred the AIO to the NR200P.

Although it's my first PC and I don't have a point of comparison, it is very well built, has the perfect size for me, excellent airflow (if I completely remove the panels, the temperature difference is 1-2 degrees) and a minimalistic aesthetic.

Tremendous case for its price with very good airflow (corresponding to Small Factor Cases in the category, which are only available abroad for 150-300 Euros). Additionally, the package includes an extra glass panel and 2 fans as a gift. Very convenient that it has front audio input & 2 USB ports. It comfortably fits large graphics cards (I have installed an RTX3060ti). The ideal cooler to match the design concept is the CoolerMaster 212 RGB, but if you replace the metal panel with the glass one, it doesn't fit and requires a trick to remove the bottom panel of the cooler (as shown in the video) https://www.youtube.com/watch?v=v9UrAXLV_Rs

It's worth every euro, I didn't expect such quality and all the included accessories, close to 100€ (edit: You steal a church for 50€). Very easy to install, all parts are detachable without the use of tools, and it looks beautiful for a minimal setup, especially if you want to place it in the living room. The only negative aspect I found is the cost for hardware such as the power supply. However, with a separately sold bracket, it can accommodate an ATX in a different position from the default, but there will be a limitation in the length of the graphics card. For better airflow, I would recommend two slim fans for the bottom and a graphics card with the smallest possible height to create a minimal gap between the card and the fans. Overall, a 10 out of 10 case, and kudos to CoolerMaster!

For enthusiasts, there is the possibility to add a 3D printed frame in the bottom, in the color of your choice, to place fans there either for convenience or to fit a cooler underneath the card. The file for fitting a regular 25mm fan outside the case can be found here:

For a slim 15mm fan, click here:

In the photo, I have the 25mm fan with an Asus Strix 6900xt LC 240.

Finally, even if you want to fit a micro-ATX motherboard, you can achieve it with a 3D printed bracket.

Like many ITX enthusiasts, I got it for its small size, minimal design, and awesome airflow. It has incredible performance for its size and the build quality is good, but I would say its selling point is the customization options.

What you need to know before getting it:
- Pay attention to the size of the power supply. While it supports SFX-L, the cables coming out of it will push against the GPU (when in the regular horizontal layout), which means you will either have to place the power supply in the front, which is not the "best" for airflow, or raise it higher, resulting in not enough space for one of the two top fans.
- The maximum fan size is 120mm on top and bottom, with the side panel being able to accommodate 140mm.
- The top fans do not screw in but attach with a special accessory. (the only "negative" for me with the case, but not a deal breaker)
- All sides are removable for easier building, top, bottom, right, left, and front.
- The NR200P version with a side panel includes 2 fans, a PCI riser cable, and of course, the side window. Additionally, it has the perforated metal for interchangeability.
- The feet are removable, and the company provides free designs on its website for custom 3D-printed ones that you can install yourself for customization.
- The maximum number of 2.5" HDD/SSD, I would say, is 3. Of course, with some creativity, additional free-placed disks can be added depending on the other components and available space.
- Regarding liquid cooling, it comfortably fits a 240mm radiator on the side, either with the graphics card in the normal orientation or at the bottom with a vertical GPU layout.

For those interested in GPU temps, in my setup, I ended up with a Deshrouded GPU in a vertical orientation with the fans of the side panel providing the cooling, and the performance is -10/15C compared to stock! I recommend it* with caution regarding temperatures and for those who enjoy tinkering
