## Description

The N400 is one of two computer cases joining the N200 in Cooler Master's new N-Series. Along with its brothers, the N400 has numerous features that help it stand apart from the competition. It does so with a full array of exciting options that have been designed specifically with cooling performance in mind, especially water cooling. Its full mesh front panel and well-ventilated layout provide for a more abundant flow of air throughout the case. Fully embracing water cooling, N400 supports radiators up to 240 mm.

Review: 7x3.5mm drive bays... PERFECT FOR SERVERS! - I bought this case for my home server. I was looking all over the internet for sub $80 cases with more than 6 drive bays. This is the one I pulled the trigger on. I could not be more happy. There is more than enough drive bays for my needs, the quality of the case is amazing, the value is fantastic, it is super easy to build in, and it comes with all the screws needed for a complete build. The drive bays were the main reason behind buying this case. There are other cases from other brands that feature similar amounts of drive bays, but at almost double the cost. The case quality is amazing, it felt really sturdy with all my hardware inside of it, there was not metal bending or anything. At roughly $75 (when I bought it) it gives a great value compared to other cases. It was super easy to build my server in this case as well, it only took me about 30 minutes for everything. Thankfully this case came with all the proper installation hardware for components, I have had to deal with some cases before that actually did not have all the necessary screws included.
Review: Very nice case to build with lots of storage - I don't tend to spend a lot on my components. I want solid, long life, but for bells and whistles I save that for the software. This lower-priced case seemed to fit the bill, so I figured I'd give it a whirl. One of the things I noticed again and again: no sharp edges. I have been doing this long enough that I remember when several serious cuts were always part of the deal when building or repairing a computer. This case has rounded all the edges, and it makes it feel like quality. Also, it improves the rigidity of the metal just a bit. The case is spacious, with lots of drive bays. I'm not sure how one would use the bottom bay, unless the drive was installed upside down (which would have its own retention issues), but I'm not using anywhere close to the available drive bays. Also, although I thought I had used up the tool-free mounting hardware, when I looked on the other side, I found some more, so I'm not even using all of the drive mounting clips. I've heard that some new computer cases have foundation panels that can be removed. While I can see that being handy, this isn't one of those cases. However, by focusing on getting the motherboard and power supply in first, it was easy to access everything I needed, and there's plenty of space to run cables behind the foundation for drives or front panel. I haven't tested out the audio, etc. on the front panel, but that's not hugely important to me. Bottom line for me: if you want lots of drive bays, including exposed 5.25" bays (for optical drives, or the like) this is a good case for a reasonable price. I added a fan on the side panel, and I understand the complaints about the meshes being impossible to remove for cleaning once the system is built, but it seems to have good airflow. I like the tool-free installation of drives, including the optical drive, and I even used the SSD slot on the back side of the drive bays. The only improvement possible for the drive bays would be to mount them laterally, but that would have airflow consequences, and the case would be slightly less stiff.

## Questions & Answers

**Q: The n400 nse-400-kkn2 seems to have a well the mb sits in.   do the standoffs raise the board enough so that side facing sata ports can be used?**
A: standoffs raise is standard like most case

**Q: Will the N400 support a standard ATX motherboard comfortably??**
A: MAYBE!If the mother board is an ATX and has horizontal connector on the front edge than NO! the N400 has a recessed motherboard tray, that blocks horizontal connectors on an ATX board.!Amazon should put a warning in their description!WHY CoolerMaster?

**Q: Can it fit a  evga geforce gtx 750ti sc 2gb gddr5 gpu?**
A: It can fit a GTX 980 Ti. Most 750Ti's I've ever seen, in-fact all of them, have been shorter than the mainboard. So you'll have more than enough room...though why not go N200 and mATX if you're going for a small and low powered GPU? I've fit a 980Ti in an N200 as well. Hope that helps!

**Q: Can I put a hyper 212 in it**
A: Yes.  I have two Hyper212s on AMD Ryzen AM4 processors in two different N400 cases

### ⭐⭐⭐⭐ Good quality name brand case at a fair price
*by W***Z on January 28, 2026*

Bought this to build out a modest custom PC. Overall quality is decent but not great. The power button is either poorly manufactured or poorly designed, because it broke within 6 months and a second replacement unit I bought did the same thing in one day. That issue aside, the interior layout and functionality worked well for me. There are also several 5.25” bays available for things like front panel USB headers or optical drives, which is rare these days on PC cases. Plenty of ventilation on all four sides and the top so there are many options for fan placement. One important note is that some current-gen Nvidia RTX 5060 and 5000 series cards may NOT fit in this case. My 4060 fit just fine but the 5060 was very snug and barely fit. Keep that in mind, especially with larger flagship graphics cards. The most appealing feature of this case is the low price. Quality control issues aside, it’s rare to find a name brand case that is this functional at such a low price.
