Great MicroATX case at a great price, I've had it a year and still very happy with it. This is an ideal case if you want great airflow in a compact case at a reasonable price. - Good quality, everything fits together well, tight tolerances, no weird gaps, didn't notice any sharp edges. - Attractive, minimalist design. Looks at home as a gamer PC or office PC. - Pretty compact for a MicroATX (many others I looked at were wider, taller, or both). - Great airflow, nice mesh design acts as a filter, easy to wipe off with a soft cloth. - Plenty of room for fans. I've outfitted mine with 2 140mm intake fans up front, 1 120mm exhaust in back, and a single 140mm and 120mm on a top-mounted AIO. - Intel 12600K CPU sees 64°C max temp with a slight OC to 5.1GHz, all power limits disabled, in Prime 95 Small FFTs for over 30-minutes. - Asus nVidia RTX 3070 Strix GPU, a 2.9-slot wide card, stays in the mid-60s range while gaming. - 5.25" bay, nice for those who can use it. I don't have an ODD, but I wanted a case with the bay to put a sensor panel. There are no holes on top of the PSU basement, but a nearly 3-slot GPU can breathe just fine in the case. A 4-slot GPU might have a more difficult time with airflow. The top has room for 2 140mm fans. The case officially supports a 240mm AIO up top. I put a 280mm AIO there (not officially supported), but had to use a 120mm fan on one side to clear the motherboard VRM. Using the 5.25" bay will prevent use of a top-mounted AIO or a 2nd case fan up top. I got around that limitation by 3D printing a custom shallow-mount bracket for my sensor panel display. Up to a 280mm AIO can also fit up front, but may prevent orienting the tubes in the preferred tubes-down orientation. 360mm AIO up front is not officially supported, but there's enough room and I've seen people pull it off with minor modding, but that would require giving up the 5.25" bay. It comes with a single 120mm exhaust fan. I didn't use this fan so I can't attest to how well it works. Only real drawback I can think of for this case, is it's so open, you can hear all the fans quite well. If you use noisy fans, you will hear them. Choose fans wisely, if you care about noise. Nothing specific to this case, it's the nature of open mesh-style cases.

This is just really a stupendous MATX case that has every feature i've been searching forever for and have never found till now. For some reason, it's nearly impossible to find every feature I want in a MATX case... I can find them all in bigger cases, but not MATX... I've found MATX cases that have some, but not all the features... until now... here's what this case features that I have always sought but couldn't find until the NR400 was released: 1) Budget priced (under $100)... check 2) Good Cable Management... check 3) Unobstructed good airflow... check 4) A PSU shroud/basement... check 5) A tempered glass window, not acrylic... check 6) Mounting points for 2.5", 3.5" and a single 5.25" drive... check I can't think of (or I haven't found) a single MATX case that had all 6 of those things in one case till the NR400 came out. The last one was also important to me, as yes, I'm one of those people who still use an Optical Drive, as I have a large collection of family photos on DVD, old games on DVD I still like to load up from time to time, and I like to do some DVD burning of various projects... for those that don't need an optical drive, I totally understand, but there are tons of nice MATX cases to choose from that don't have an ODD bay, and so few with a bay that have other nice modern features. Anyways, i'm rambling... on with the review... The build quality is really nice for $59... I love everything about this case... if there are any complaints about quality, i'd give a slight mention to the back panel of the case being a tad flimsy, but this is more due to its extreme perforations for airflow and the lack of an I/O shield being there for support when you take it out of the box... once your build is complete, this stiffens up. The only other thing I don't like about the quality is the bottom PSU intake filter... it's kinda lame... just a cut plastic sheet that bends into place... i would have preferred something a little more "pull-out, push-in" like on other cases, but at $59, if this is the only grumble, it's forgivable and not enough to deduct a star. Airflow on this case is just awesome... there are far too many cases with terrible airflow... solid front panels or perforated panels that are far more metal than air (I'm looking at you MasterBox Q300L) that turn your PC into an oven. The NR400 has none of those problems... as with any case, I immediately tossed-out the stock fans and replaced them with three upHere 120mm fans... two up-front as intakes and one in the rear for exhaust... although there's nothing wrong with this setup, I wanted more and realized I could have more... so I upgraded my two front fans from a pair of 120mm fans to a pair of 140mm fans (also upHere). This really kicked up the airflow quite a bit (and is what you see in my pictures... the pair of 140mm fans up-front). This is a Haswell Core i7-4790 build using only air cooling (A CM Hyper 212 Black Edition), and at idle, i'm running 25-27 Celsius... under load in games, my CPU is usually in the mid 40s to low 50s tops. My GPU (a GTX 1660Ti) is anywhere from low 50s to about 62 tops, depending on the game and what's going on. This case just stays really cool with air cooling alone. Other features... cable management is easy with this case... it's easy to keep the viewable front of the case clean, as there's plenty of storage are in the back to hide your cables... there's four dedicated 2.5" bays, which have a unique "rubber gasket and insertable pin" arrangement to attach your SSDs to. Simply screw in four pins (included with the case) to the bottom of your SSD, and push into the gasket... it's held on with friction, stays in place, but easy to remove (see pics). Also, there's a removable and repositionable 3.5" bay under the PSU shroud... the bigger NR600, it's riveted in place, but on the NR400 you can move it or remove it, it's up to you. As previously mentioned, there is a single 5.25" bay which is rare in a case like this, and I'm happy to have it in a case this nice. If you don't want/need the bay, it is also removable to clean up your build. I really love this case... as it just came out in 2019, it was not available the last time I upgraded my case for this build. I did have my system in a Fractal Design Focus G Mini (another case I really liked, but not as perfect as this one)... however, I liked the features in this case so much, I went ahead and got it to switch my parts over to this case... it's that awesome, and i'm glad I did it. This is really a great case for the price. 5-Stars! Update 2022: yes, it fits an EVGA FTW3 3070Ti as well... pictures updated.
