NR400

Compact case that can fit more components than many newer generation larger cases. Very useful if you want to add a few HDD for storage. Can actually fit FOUR 3.5" Hard drives (or even 5 HDD if you put an adapter or removable 3.5" drive bay in the 5.25" front bay, and still has 4 places for SSD installation on top of that (or far more if you aren't installing any 3.5" drives). Admittedly, getting everything in can be a tight fit, but looks clean once everything is installed. Also has the window panel and mesh front and top so you can throw in some RGB fans if you feel like it for the "gaming case" style/ or for just better air flow. Good amount of room for most GPUs as well. Not a bad compact case for a media storage, gaming, HTPC or whatever. Definitely one to consider if you want better 3.5" storage options vs most modern 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)... check2) Good Cable Management... check3) Unobstructed good airflow... check4) A PSU shroud/basement... check5) A tempered glass window, not acrylic... check6) Mounting points for 2.5", 3.5" and a single 5.25" drive... checkI 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.

This case basically suits all my needs.- House a whole mATX build in it and still manage to have some wiggle room.- Provide ample airflow.- The inclusion of a 5.25” external drive (e.g. DVD drive).- High quality build.- Cable grommets.- Power supply basement.- Store 3.5” hard drives and 2.5” SSDs.- Have a recessed rear I/O design, which is still standard with most cases, but some cases do not have this.- Actually save some desk space.However, the main issues:- No perforation on the topside of the power supply basement. Coming from a Phanteks Eclipse P400 (though with a front mesh panel added two years after purchasing), this tells me that the perforation is desperately needed for proper airflow from the front of the case all the way to the graphics card. The graphics card I have installed has barely half an inch to be able to breathe, and with the case acting mostly as a heatsink, this makes it easier to recirculate the same hot air the card and the hard drives are already putting out. However, it may not be a huge issue if I upgrade to a newer card that is 2-slots deep without it going too hot/point of thermal throttling. And for almost $90 (that’s how much I paid for this case; sad, I know), I would ask for much more than just a fully stamped metal frame. (The P400 and now the P400A was a little cheaper in comparison, and still provides adequate airflow on all fronts, so I doubt Cooler Master has much of an excuse for this.)- Tempered glass. It is a high quality tempered glass side panel, but it’s one more thing to put more on maintenance for. I would much prefer Cooler Master to be able to have their consumers *also* get the option to have either a fully metal side panel or a metal side panel with some perforation closest to the graphics card (basically in line with how the N200 had it) with the case, so as to have a more professional look than just reinforcing the weird gamer aesthetic that seems to be out of place. Thing is, the entire case seems more or less *designed* with “professionalism” (the whole “office” look) in mind, rather than heavily catering to gamers. So, yes, I do find this to be somewhat baffling. It makes me think that the glass side panel basically inflated its overall price, and not just because of the fact that during the manufacturing of this case, the cost of steel went up in the past year. (I’m pretty sure it is still relatively up there right now.)- Cable management points are very minimal, and spacing for it leaves a bit to be desired. As much as there is still a bit of room left for extra cabling and somewhat properly route your cables, the side panel door for the back shows the case’s overall limitations for most cables, especially SATA power cables. It’s unfortunate, but it could have been much worse—as bad as its predecessor, the N200, which has almost NO room for rear cable management. Not even for the mATX motherboard it was built for.- The rear cutout for the motherboard is a little too short. It makes it virtually impossible to add on a third-party cooler without having to either take out the motherboard, or add the cooler *prior* to installing the motherboard (depending on what you’re doing). However, this also coincides with the space needed to make the integrated SSD mounts on the rear side of the case, so I can’t say for sure how that could be really improved upon.- This doesn’t really include any velcro straps within the case for rear cable management, which is somewhat disappointing from a convenience standpoint. However, my power supply has them supplied, albeit they’re a little thick.- The bottom intake for the power supply has only just a square mesh that is barely held onto by tabs, and no mesh cover with a frame. This makes it bring about issues with maintenance and the ability to keep most dust out of the power supply.Overall: for a budget case, this is quite a lot you can ask for, but a lot of the shortcomings appear to be unique to my scenario, rather than in most cases where this may not be a problem—but the issue with SATA power cables still stands, since this case is designed to include a SATA-powered 5.25” drive.
