Cooler Master NR200P MAX SFF Small Form Factor Mini-ITX Case, Custom 280mm AIO, 850W SFX Gold PSU, Triple-slot Vertical Mount GPU, PCIe Gen4 Riser, Tempered Glass or Vented Panel (NR200P-MCNN85-SL0)

Can fully break it down with only a screwdriver, very accessible. Well thought out design, plenty of fan mounting points. Great venting for air flow with metal mesh filters to keep out animal hair, etc.

Tiny case with ample amounts of air flow to keep even the most high end components cool. Relatively easy to build in unless you’re adding a radiator/custom water cooling. Insane value here.

Overall, the case is very well built and easy to build in, which was great. One problem though - because of the design of the MAX version of the case, where theyve moved the motherboard down to fit in the top radiator, you are forced to use the riser cable to mount the GPU to the motherboard. No problem, I thought. If it goes bad, either Ill just replace it or Ill RMA the riser or something. Surely, Cooler Master has thought this through. (Spoiler: They didnt) Everything worked fine for awhile, it seemed, but then I started getting random crashes. Oh no! Tested all my hardware, then ran it all together but without the riser - no problems. Assemble it again, and boom - problems immediately back. Yep, its the riser. So it shouldnt be a problem, right? Just get a replacement and youre good to go? Nope! The company is unable to honor the warranty in a timely manner, because the parts are backordered and they have no idea when theyll be in stock again - all they can promise is that itll be Q3 of this year. And since the graphics card MUST be mounted with the riser cable, which is so absurdly short you wont find a decent replacement anywhere, you will be essentially left in the dust if yours dies on you, unless you just have extra cases lying around for some reason. Thank God Amazon decided to come through and give me a refund, because otherwise Id be stuck with my riser in my hand, if you know what I mean. TL;DR - It was a great case, but when it relies on something as finicky as a riser, youd think theyd be better prepared for the issues thatll inevitably arise. Not so for Cooler Master - at least, not this time. My advice, either avoid this case, or simply wait until the supply issues are resolved. Or, if you have money to burn, I guess just buy one and pray yours lasts longer than mine did.

NR200 is a solid sff case and anyone whos built in it can vouch for it. Nothing else more to really say other than the case can fit a lot of high-profile air coolers and often times performs better than most 280mm AIO setups in a sff like this. My only complaint is that the cases top lid came with a missing screw and notch, so it doesnt securely snap on and stay on as well as it should. Also on the left side panel, the magnetic mesh filter thats on the inside was bent. You can clearly see that it was either folded in half somehow or maybe smushed in, because theres a vivid streak straight down the middle. Other than doing some more QC, CoolerMaster case doesnt disappoint.

All panels come off which makes it easy to access everything.

This case is so easy to work in for its size. I have the mesh panel with a noctua U12-A fitting just fine, I do not think it would fit with the glass panel. I like that it has dust filters all over, it is certainly catching a lot of dust in my city apartment. The case comes apart with a tool less design so easy to clean out when I need to do so. I have an aggressively quiet fan curve for my 3700x, so its pretty much silent during any desktop activity. Only in games do I hear it a bit (the case is right behind my monitor), the airflow is fantastic. I have the cpu heatsink with two fans (airflow to the rear, so functioning as exhaust), no dedicated exhaust at the back as it wont fit with such a larger cooler. Then two exhaust at the top (noctua nf-p12) tied to cpu temps instead of system temps. Other small cases I dont think it would be as silent. You can fit pretty a large graphics cards with no issues. I think Ill be using this case for many years to come unless something changes drastically in terms of motherboard formats. I came from the NZXT H200 and my temps improved a lot with all the extra airflow so my system runs more silently due to fan rpms being lower.

Only have 3 PCIE lines, one for CPU, and two for GPU If you want to build rtx40 graphic card, you may need to buy one more PCIE line.

The ITX space is growing but still has limited options. This case checks most of the boxes for ITX build but my only concern is the custom AIO in the case. Just know that if you ever have an issue with your AIO you can not buy another brand or even a CoolerMaster off the shelf. This is a custom built AIO for the case so if it goes bye bye then you have to work directly with CM to get another. In my case I purchased 2 of these. The first one was fine but there must of been air bubbles caught in the pump because it would constantly crackle in that area. I disconnected all the fans and even the gpu and ensured the sound was from the pump. I purchased another and it seemed fine but once again after a day of use I started hearing the crackle. I contacted CM and they were great but they were going to have me send it in. I didnt want to deal with this down the road. There are many ITX cases that you can build with off the shelf parts so if something dies or goes wrong you can quickly get a replacement. Case is awesome but I wish the AIO wasnt custom. If they could design it where you could use any 280mm AIO that would be a 10/10.

Its a great case as long as your good with wire management

This case is great. You can fit a 3.5” hdd inside of here if you are mindful with your cable management. A little hard to see but the second pic was my 3.5” hdd configuration before I upgraded to an ssd.
