  • Great case with lots of air flow with the preinstalled fans
Paired this with a MSI MAG 870X motherboard and MSI MAG E240 AIO CPU cooler. The case says it can mount a 360mm AIO cooler on the top where I mounted mine, but I don’t know if that’s true since the CPU power cables that attach to the motherboard were kind of blocking the liquid cooler from sliding all of the way to the back of the case. The ARGB control system on the case made connecting all of the fans a breeze, just remember you’ve got to hold down the LED button on the top of the case for 3 seconds to get them to program with MSI Mystic Light controls. Coming with four preinstalled fans made this a great value and the case gets plenty of air pulled into it. Somehow managed to become infested with xenomorphs, but it’s not enough to knock off a star. They mostly come at night…mostly… ... show more

  • Great Product from MSI
Awesome case with good airflow. Easy build with this one. Has good cable management. I did not use any SATA drives in my build but it does have mounting options for SATA SSD and HDs if you need it. Keeps them hidden away for a clean build.

  • Nice case, has 3.2 usb.
Very nice case for the money. Fits large modular power supplies by removing the 3.5" disk tray. Has fan controller which is nice. Good airflow, but needs 3x 120 or 2x140mm fans to keep temps reasonable. Can fit 2 360mm radiators, possibly 2 420mm radiators.

  • Good for price. DIY your own dust filter
Good case easy to build in. Nice fans pretty quiet in my opinion. Only problem is that the front intake does not stop dust AT ALL the mesh barely stops any dust. Gotta DIY the mesh yourself. But other than that it is a good case for its price. LED Hub janky though.

  • Great solid case with fun ARGB fans
Great price for a case that was large enough for all our components. Easy cable management. Nice ARGB hub which worked with our CPU cooler. **If you're looking for the case screws and motherboard standoffs, be sure to check one of the HDD drive bays. We ended up going to the hardware store because we couldn't find them. We used M.2 storage so didn't even think to look in the bays. ... show more

  • Good quality case especially at its price point
This case is fantastic quality. The fans are quite silent, even on high. Airflow is excellent. Cord management is very good with well thought out placement of channels to place cords through. There were plenty of extra screws. The price is quite great for such a quality case. My only gripes are that the PSU shroud makes installing cables for a modular PSU quite cramped. A magnetic filter could be used for the front, like is included for the top, as the holes do allow quite a bit of dust in. And that the screws aren't great quality, and do easily strip. One of them stripped while installing the motherboard and could end up being quite the pain in the future. ... show more

  • It is a case for a motherboard
It's an okay case not quite as sealed as I hoped for but definitely works okay I got this because I needed a large enough area for my water cool with a little bit of removing and re-adding fans I was able to make it fit.

  • Solid case for the price
Honestly a great price for a case that comes with a lot of nice features. The 4 argb fans and the fan hub included are very nice for the price point of the case. Very pleasant to build in with minimal trouble. The only things I can complain about with this case is that the PCI slot covers are single use, however they do provide two screw-in covers in the case you pop the wrong one out or change slots. The other thing that gave me trouble was the motherboard stand offs. I had to install 3 to fit my full ATX motherboard, but for some reason the standoffs kept threading in sideways, after a few tries they finally went in correctly and let me finish my build. Other than those small complaints, this case is definitely worth the price and I'm so glad I went with it. ... show more
