    from completed build Sleek NR400 Build

    Initial quality of the case seems good. I believe GamersNexus had a QC issue with the big brother of the NR400, the NR600, where the glass panel wasn't flush with the front of the frame. Thankfully my NR400 doesn't suffer from this. I haven't found any sharp edges (yet), and overall haven't found anything to complain about regarding quality.

    The tempered glass side panel is inside of a slim frame that makes it easy to handle. Unlike its big brother, the NR400's drive cage in the basement is removable, which means larger (see: normal size) PSUs will fit in it. Unfortunately, Cooler Master confirmed that the version without the ODD bay will NOT be coming to the US, which was a bummer since I wanted that version for the clean slab appearance of the front mesh panel. Fortunately the ODD bay is removable with four screws that are easy to access, and the slot in the front doesn't bother me as much as I thought it would. I was able to fit two 140mm Silent Wings 3 fans between the front grille and the frame with ease, and cutouts for their cables were conveniently placed for routing. Cable management is decent, though at this price point I didn't expect it to blow me away anyway.

    Overall, if you're looking for a high-airflow case in the $50-70 USD range that would look nice as gaming or office PC but somewhat sheds the gamer aesthetic, this is my recommendation.

    For the price, you're getting a pretty solid mATX case. I was looking for something of its size with a tempered glass side panel, plenty of ventilation, room for cable management, and a PSU shroud- all of which this has. Build quality is pretty good, and it's easy to disassemble. There's a good amount of room under the shroud and behind the motherboard tray for cable management (more if you remove the hard drive tray). Overall a great case for what you're paying.

    Also, for anyone planning on using this case: PCPP claims most power supplies are too big for the case, when they actually aren't. The hard drive cage is adjustable and can be moved. When it's in the furthest position back, it might block your power supply, but it comes preinstalled closer to the front of the case. You shouldn't have any issues putting your PSU in unless it's really long, and you can always remove it if needed.

    Great airflow but not very good for first time builders as with most MicroATX cases. It looks nice and has cable grommets at its price so it's great anyways.

    from completed build Monochrome.

    Good airflow in a MicroATX case is rare, but this lil' case has it plenty. It has such a nice and elegant look which was what I was looking for. Plenty of space inside to work and do cable management. It is also very easy to clean due to the mesh front panel and the magnetic dust filter it has on the top and the bottom.

    It comes with two pre-installed 3-pin fans and I got a nice surprise when I discovered a molex fan splitter pre-connected on the front fan! This goes connected directly to the power supply and you can hook up to three fans in this way! Not counting the ones you can connect directly to your motherboard, so if your motherboard has 2 additional fan connections (which most micro ATX motherboards do), you can hook up to five fans in this case without the need to get a fan splitter! Talk about value!

    The only downside is that cable management can get a bit cramped if you're using a non-modular power supply, but nothing that a few rubber bands to hold the remaining cables cannot solve. Overall I'm very satisfied with this case I totally recommend it!

    Very easy to work with, cable management was a breeze. You can remove the HDD bays on the bottom to create more space for your PSU if need be.
