## Description

From the manufacturer Since our founding in 1992 as a thermal pioneer responsible for the first ever heat pipe heatsink, through our evolution into a manufacturer of cutting-edge cases and peripherals, to our recent groundbreaking switch to the modular format, Cooler Master has consistently rewarded its customers and fans with the utmost in innovation, choice, and control. N400 ATX Mid Tower The new Cooler Master N400 is a mid-tower designed for optimum cooling and expandability. The front panel and I/O area feature the premium mesh for a modern look. It supports up to 8 fans, including two pre-installed XtraFlo fans for extreme high airflow. If you prefer liquid cooling solutions, installing 240mm or 120mm radiators in N400 won't be a problem as well - the 240mm radiator can be installed at the top or on the right side, and the 120mm one - in the rear. N400 also provides plenty of expansion by support of up to 3 SSDs and high-end graphics cards up to 320mm / 12.6 inch. Max CPU Cooler Height 164mm / 6.4 inch Max GPU/PCI Card Length 320mm / 12.6 inch Supports a 240 mm water cooling radiator or two 120 mm fans on the right side or top of case Three dust filters (top, right side panel, and power supply) for easy maintenance

Review: Not suitable for modern Motherboards, Coolers or GPUs - The N400 offers a decent number of drive bays and airflow options, but several design choices made the building experience more frustrating than it needed to be. * The PCIe slot covers are flimsy and do not provide much support for add-in cards, resulting in poor alignment with the motherboard slots. * Only two of the 3.5” drive bays include tool-free mounts, while the rest require screws. * The 2.5” SSD mounting system is also of low quality and difficult to manage, making cable routing more challenging than it should be. * There is very little space above the motherboard, which makes it difficult to connect cables, especially when using a tower cooler. While the case technically supports two fans in this area, there is realistically no room for them if a larger air cooler is installed. The same goes for the two fans which can be installed behind the drive bay, as they share the same space as the 2.5" mounting adapter. * The case is not designed with right-angle motherboard connectors in mind, meaning compatibility may vary when using SATA, USB, 24-pin power connectors etc. * The included fans are functional but do not compare well with modern, quieter alternatives. * The dust filters are not easy to remove for cleaning. * The case does not come with common motherboard standoffs pre-installed (e.g those shared by both ATX and mATX), which adds an unnecessary step to the building process. * There is no AIO support here. You might get one mounted on the rear 120mm fan, but that isn't going to be enough for modern hardware. If a budget case with storage capacity is the main priority, it can be made to work, especially as you'll be saving a lot of money vs alternative high-drive capacity cases.
Review: Amazing value for a very attractive computer case! I got this for $40 on sale, and it was worth every penny. The metal case is light and mostly strong. Some points are a bit delicate, like the front panel fans and gpu shield thing. The magnetic front panel is great for quick cleaning. My PC takes up less space while looking attractive and keeping my internals cooler than before. I appreciate the cover in the bottom of the case to hide the extra cables from my non modular power supply. Everything but the 3.5 drive bay from my mid tower case fit great into this case.

## 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

### ⭐⭐⭐⭐⭐ Review
*by J***D on 14 December 2016*

A great case for those who want a simple yes classy design. Enough room for several additional fans if desired, and was mostly easy to work with. Some areas are a bit tricky to deal with compared to some cases that make life simpler, but everything is made solid and most of the case is metal, so there isn't really any cheap plastic involved. This makes for a sturdy case with decent room for whatever you might need in any good-tier computer builds
