Cooler Master N400 - Mid Tower Computer Case with Fully Meshed Front Panel (NSE-400-KKN2)

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.

I used this case for to build out a NAS. It has plenty of slots for drives and was easy to assemble for someone like me who never built a computer before. Had great airflow as well. Also it comes with all the screws you could ever need to mount things.

Seemingly far and few today, this is a standard all metal business class ATX computer case, but with some hindrances.Using a Gigabyte Z790 UD AC ATX motherboard, the interior is quite small and tight after power supply cables are connected to the motherboard and trying to connect SATA cables to the SATA header! SATA motherboard header has very little clearance between the rear of the storage drives and SATA header.Shrugs as to why the SATA header is always a 90 degree angle.PROS1) A standard/business all metal computer ATX case.2) Apparently decent working dust filters.3) Power button is lit, however only lights when unit is turned on.CONS1) Little clearance between the 90 degree SATA motherboard header and rear of storage drives. Seems more so a motherboard concern, however still very little clearance between motherboard and storage drives.2) Interior of the case is black, everything is black, making seeing and distinguishing parts very difficult. I usually prefer readily light refracting white interiors, making interior lighting almost not necessary.3) Push buttons on the front of the case are black, requiring additional stickers for distinguishing the buttons.4) Difficult to distinguish the front USB 2 ports from USB 3 ports, again requiring additional labeling/stickers. A minor note.5) Some of the plastic storage drive securing fasteners are finicky or difficult to work with.6) Vertical sides of drive bays are extremely tight! No indications of shipping damage, so likely plan on a very tight sliding insertion or removal removal for your spinning hard and optical media drives!7) The PCI face plate base slots are either extremely tight or bent/damaged, and purchasers may not know until after the motherboard is secured! I had to use a small diameter long tool pick for prying some of the base slots further open from an apparent bent position!8) For a desktop computer case sitting on the floor, the power switch sits extremely low to the ground. Required adding an external power switch, couldn't think of bending over every day for power-on, unless using wake on LAN!9) PCI case non-reusable slot covers are lightly welded and should be immediately removed prior to motherboard installation! Else the motherboard components can be exposed to loose metal shards during removal! Shrugs as to why the case manufacture did not include reusable PCI slots, had to also order extras myself, as well as the larger thumbscrews, as the smaller screws can easily get lost within the motherboard components.10) I wasn't aware the back panel had already had 3/8 to 1/2 inch diameter external wiring ports. Easily overlooked. Did not see the lightly welded plate diameter holes, until I had already drilled, fitted and installed a reusable PCI slot cover with a rubber grommet and wiring!Otherwise, probably a far better case than most of the other Plexiglass computer cases nowadays!
