Big SFF case with some caveats
15 April 2021Anonymous

originally posted on newegg.com

This case it's great, very nice looking, lots of space, easy to open and you can remove the screws on the corners for even more space when putting everything inside. However, when you're building, you notice some small caveats. My biggest problem was the my SFX-L PSU pushed my 330mm GPU downwards as the cables are too stiff and connectors are too long. I recommend using an sfx PSU instead. Another problem it's that the side mounted fans make little difference in temperatures, intake, exhaust, no fans, not much difference. This area it's better reserved for a radiator. Another problem I found was that my mobo has a back SSD slot and would get to 90c. I added a thermal pad between the SSD and the mobo and a copper slim heatsink and they improved to 70c under load. ... MoreThis case it's great, very nice looking, lots of space, easy to open and you can remove the screws on the corners for even more space when putting everything inside.

I added a thermal pad between the SSD and the mobo and a copper slim heatsink and they improved to 70c under load. Finally, if you decide to go liquid cooling, there's not a lot of free space between the PSU back and the left panel, so fitting a rad with a 25mm fan might be difficult, also if you are going custom, getting a pump/reservoir to fit in the back of the PSU also might be a difficult task. However, consider that my GPU was 330mm, probably a smaller GPU or using a GPU water block will free up lots of space.I had a very small case before this one, so this one feels huge, but there's no way I can fit a 3090 on my previous case. Also please consider that I loved this case and I'm mentioning things that complicated things a bit, but by no means I think it's a bad case. These are things that I recommend keeping in mind, that's all.

Compact, well vented case, some issues though...

Everything about the case is exactly as I expected it to be except for a small handful of issues. All the measurements were up to spec and as anticipated for my client. However, the second fan provided in the case will hardly be of any use to you if you want the fan properly secured since it only ship with rubber gromets and plastic inserts, so don't bank on the second fan saving you much money on a cooling solution.The power supply mount was a fair bit difficult as well even considering I purchased a fully modular power supply to go with this case. You only have 2 real options for mounting the PSU being internal cables facing up into the chassis ceiling, or down into the chassis floor. I opted to install it facing towards the floor of the chassis for the sake of ... MoreEverything about the case is exactly as I expected it to be except for a small handful of issues.

You only have 2 real options for mounting the PSU being internal cables facing up into the chassis ceiling, or down into the chassis floor. I opted to install it facing towards the floor of the chassis for the sake of room and easier cable run, however once we got around to installing the graphics card things were made SIGNIFICANTLY more difficult. Thankfully we managed a way to actually use the cables as a sort of card support to prevent the card from flexing too much but it was still pretty dodgy getting everything crammed into the appropriate areas without breaking or straining anything.Beyond those few issues the case is otherwise perfect. Plenty of modularity and one thing cooler master actually did that they didn't have to (And I'm personally a HUGE fan of) is they did include a fan splitter in the case! Which saves you a bit of money and goes to show that they do understand the market their shipping these into and care to make these a bit easier on the consumer-end for people who may not fully understand the short comings of cases like these (And the motherboards they're intended for by extension)Despite those few issues, the case works amazing and you can really feel the airflow from the case. Every single vent except for the rear vents as a mesh dust filter which is great and the panels are incredibly easy to remove but not so easy that you're worried about them popping off during transport. Very intuitive case and when the time comes for another project using ITX parts I'll definitely be ordering this case.

Fantastic Mini ITX PC case

originally posted on bhphotovideo.com

Thinking about building a small form factor pc, then this is the case for you, it's not too big and not too small, and plenty of ventilation to keep your hotter pc components cool. Alongside youtube I was build an awesome gaming pc and keep my AMD Ryzen processor cool with this case, a definite must-buy.

Good looking case with excellent air flow
15 June 2022

I have seen many YouTube videos on this case. It's so easy to open the sides. There are no screws, you just pop the sides out. I wish they make vented front panel and also a pci riser cable for vertical mount graphic cards.

Great mini iTX case
23 December 2021

I had upgraded to a 2.9 slot gpu which was not going to fit in my evolv shift air rev 1. And as much as I loved that case building in the rev 2 of the Air was a bit more of a challenge than I really wanted this time. The NR200 was really easy to build in and has tons of cooling. The build went together really easily and a few days later I decided to add 2 more fans and it was so easy to pop off a side panel and the top toss on a few fans and pop it back together. It's a good looking iTX case and for the price a good value too.

Small, classy, cool, quiet
14 May 2021

I switched to this case from a compact tower, and love how much smaller my system is. It can now fit on my desk, which saves me some room. The case is mostly metal (steel?), and it looks classy as heck.I removed the Cooler Master fans that came with the case, and installed three Be Quiet fans on the top and rear instead. I recommend this change - the Be Quiet fans have a much nicer sound profile. The Be Quiet Pure Rock 2 CPU cooler just barely fits in the system.Despite having mesh openings on most sides, this case is whisper-quiet when idling, and very reasonable when gaming too. The airflow from the mesh might actually contribute to the system being quiet, which is a bit counter-intuitive to me, coming from systems with solid side panels and sound damping.

The noise profile is especially nice given that this system now sits next to me on my desk. If higher-end parts were installed, it might be a different story, but it's fine with an R5 3600 and RX 470.

The best mini-itx price/performance
18 January 2023

I just move all my components (except motherboard and power supply) from an mid-Atx case to the NR200, and I was able to keep the same temps I had in the bigger case. Rtx3090 (from an Alienware PC) Ryzen 9 5900x, 64Gb Ram and 2Tb m.2 ssd drive, 850w SFL Power Supply.

Well-designed and easy to work with
30 January 2023

Aesthetically clean and uninteresting, but functionally fantastic. Basically every side can be removed independently, which is great for building. Instructions have no text but are generally clear (and come with lots of different configuration ideas). Included fans are solid. Love the magnetic removable mesh dust covers on the sides. Motherboard standoffs are built-in and extra screws are also in the box. I bought the most popular ITX case and I have no complaints!

What a great little case

it wasnt my first choice. 3.5 eggs
16 April 2022

my main disappointment is the lack of usefull usb ports on the front panel, i didnt even bother wiring it to the MoBo. im just glad i can mount my gpu in a traditional manner. while gaming i get 52c-64c on my i7 12700k stock gpu is a msi 3080 12gb z trio and at 90% fan speed it runs between 72c and 80c which is too hot for me.
