Cooler Master MasterBox NR400 Tempered Glass Micro-ATX Case

Solid case all round.Price and performance pretty good overall.Small issues with standoff insertion (more use error).Fans slightly noisy but that can be fixed with aftermarket case fan.

Nice compact case. Pretty easy to work in and a nice understated sleek look. Nice quality for the price point. Ideal case for a budget build.

good airflow and looks pretty good, i like how the glass panel has a border this makes it so if you install an RGB strip around the inside you cant see the hotspots, good airflow 2 fans included which is great. Very good value.

Good case - like a tardis; plenty of room to build inside, but small form factor on the outside.Really, that explains it. It's a simple case without any sound deadening material. It looks classy, air flow is very good, and there's plenty of room to move cables around, etc while building. All in all very happy with it.

Budget Case = Fantastic Value

This is my first case from CoolerMaster and it will be my last. Not because it is bad and awful for cable managment, which may I add it has plenty of room back their or that it has knocked 10 degrees of cpu temps. Quite simply I will not need another case ever again.This case deserves a review because CoolerMaster have not ripped off the consumer. Granted their is parts of the case that is budget metal, but I say this, when are you going to touch the insides again after a build? When a case like this has been designed and thought out for a mATX or in my case ITX and can take a 280mm rad up front which is the best placement for a CPU rad.My system specs;CPU: i7 8700k 5GHz Vcore 1.275vCPU Cooler: NZXT X62 280mmMotherboard: Asus Z370-I GamingGraphics: Palit ... MoreThis is my first case from CoolerMaster and it will be my last.

A smaller form factor PSU like SFX would probaly do the trick or those fancy slim line PSU cables will fix the issue.If you have read up to here without skipping to this point well done enjoy your purchase.

Good value case

This is a nice well presented case, it has decent enough cable management, plenty of routes to keep your PC tidy, the tempered glass side panel is nice.It has adequate ventilation and have not experienced any thermals outside of what I expect.the quality is good and on price point.

Great Case! With one complaint..

This would be a 5 star case if we could get it without the optical disk drive. Outside of that, I love this case. Was super easy to build in and looks great. The ODD only lets you get two 120 fans in the front. Without it, you could easily fit three. You can put the fans on the inside of the case and make it fit three, but aesthetically it looks terrible from the outside looking in and the top fan sits on an angle and you can only use two screws to secure it. Case has just enough room for a 240mm aio up top and a 120mm aio out the back. I would buy again for another build for sure despite the ODD. I would just use two 140mm fans up front instead possibly.. oh, yea.. plenty of room and tie down points in the back for cable management too. I am extremely happy with ... MoreThis would be a 5 star case if we could get it without the optical disk drive. Outside of that, I love this case. Was super easy to build in and looks great.

The Perfect Grampa Box

This is my first build with a mini-tower, which I have avoided in the past because I thought there wouldn't be enough room inside. I was incorrect in that assumption. There is 'both hands inside' enough room! I also wanted to install an optical drive and this is one of the rare cases that gave me that option. It's quiet too, I need to look at the lighted power button to ensure its off when I do a shutdown. I like its looks and styling. I'm not into RGB LED so the glass panel wasn't necessary, but that's a minor negative. And, for what I got, the price as more that right. I'd buy it again in the future without giving it a second thought.

Tim's review of Cooler Master Masterbox NR400 with ODD Tempered Glass Mini Tower Case

Pros: Very good options for cable management. Plenty of room for cooling fans in such a small case too and the front filtration is good at catching dust.Cons: Maximum depth for the front fans for the included mounts to work is about 25mm (not documented), so the 140mm's I have didn't fit without modification.Front filter requires very frequent cleaning - although it is being used in a fairly dusty environment!

Very good apart from cable management

I bought this case after reading several reviews and research. I have a ASUS b450 TUF Gaming mobo, Rzyen 5 3600 CPU, Sapphire Pulse Radeon RX 580 8gb GPU, 16gb Corsair Vengeance RAM. WD M2 500gb internal SSD and an old 2tb WD SATA external drive. I also bought the be quiet! 600w PSU.The supplied case fans aren't up to much but I've kept one as a rear exhaust and got a 5 pack Deep Cool RF120, 3 as front intakes and 2 as top exhausts.I would say that the air flow in this case is great, the build quality also. I love the glass side panel.On the downside, the bottom edge of the mobo is very close to the bottom panel in the main enclosure and with a double height GPU, installing the connectors safely and cable management is a bit tricky. Also there is very little ... MoreI bought this case after reading several reviews and research.

I love the glass side panel.On the downside, the bottom edge of the mobo is very close to the bottom panel in the main enclosure and with a double height GPU, installing the connectors safely and cable management is a bit tricky. Also there is very little space between the rear of the mobo and metal side panel. With using the hard drive bay and having fixed cables on the PSU, there is very little space for cables (plus I have the Deep Cool fan controllers) and it's really tight and messy.With hindsight, I should have bought a PSU with modular cables, so only installing what I needed, and if I replaced my old legacy SATA hard drive with an SSD I could have removed the drive cage.In summary, a very good case but weak on cable space which could be improved by removing the hard drive cage and using a modular PSU.
