  Incredible for a Micro-ATX case

  I always build Micro-ATX because I don’t need a larger form factor, and have gotten used to small, cramped cases. This case has plenty of room for everything, and plenty of spots to hide cables. It comes with magnetic top and bottom filters, and the front of the case is also fully magnetic, allowing for easy removal for cleaning, and fan installation. Compared to my other cases I’ve built, this one was the easiest.Ver másVer menos

  One of the largest mATX case that fits an extremely large GPU

  TLDR: THIS CASE FITS ONE OF THE LARGEST AND LONGEST GPUS AROUND THE MARKET (XFX 7900XT BLACK EDITION WITH Z SUPPORT BRACKET). IT ALSO IS ONE OF THE MOST HIGHLY VENTILATED CASES I'VE SEEN.I rarely write reviews, but this deserve one of those moments.I really like this case. It's not expensive for what you're getting and the 360 AIO Liquid Cooler front and top mount is really rare in a mATX case specifically. This also fits GPUs around 380mms of length. My GPU, XFX 7900XT, fits in this case with a bit of length to go, although, I had to top mount my AIO, Arctic Liquid Freezer 3 360, which is still impressive as I had ease installing my parts in this case.Additionally, this case has 5 PCI cover slots that are REUSABLE. Many cases in this price point are only removable but not reusable; this is such a nice inclusion to this case. Also, it came with all the screws and even zip ties to complete my re-casing of my PC. Build quality is better than anything I have seen at this price point. No sharp edges, a lot of spaces to hide and route cables. PSU and Motherboard power cable shroud is present. Front panel is easily removable for cleaning and actually building a computer.This case also comes with two EXTREMELY LARGE FILTERS: it spans almost the whole top and bottom of the case which are also highly perforated for cooling.DOWNSIDE:It DOES NOT COME WITH ANY FANS. This is a budget price point. Many people who are looking to use this case are in a tight budget. It would have been nice to at least include one or two fans with this case.Overalll, this is one of the biggest compatibility mATX case there is. It has class leading GPU support and ventilation. 360 AIO Liquid Cooler support in front AND top is hard to find in ANY mATX case specifically.Ver másVer menos

  Really good case for the price.

  If you just need a case for an matx motherboard, then this one is really nice with a lot of space. I know people will say the sama 01 or the lian li a3, but if you just bought an matx motherboard for the cheaper price and you don't mind a case the size of an atx case for a cheap price then this case is for you. Just gets really dusty on the outside if you live in a very dusty area.Ver másVer menos

  Almost perfect!

  I've built many rigs and this case has everything I was looked for plus BTF connection for my back to the future build!

  Great Case but Poor Quality Control

  The case design and build quality is great. It is great to build in, with plenty of room for cables and everything needed to make a monster matx build. The airflow is fantastic, one of the most ventillated cases I've seen, for example the entire back of the case is perforated with high porosity, same with the bottom of the case, places you dont normally expect to have great airflow.One of the beautiful features of this case is that it has one extra pci slot below the matx motherboard, which gives you room to install fanst below a chunky gpu to get it more airflow. This helped bring my GPU temps by 10c vs my previous matx case with no bottom ventillation.Another awesome feature is the height above the motherboard leaves plenty of room for larger/taller AIOs and radiators, such as the arctic one. This is one of the few cases that you can put in a chunky 280mm that is tall on top of the case and not obstruct any part of the motherboard.One major caveat to otherwise perfect case was quality control on mine, one of the rivets that holds the pci slots was not punctured through the cage, so the cage was hanging on one side and a rivet prevented it from resting flush against the back of the case. I had to spend time and sweat to drill out the rivet and replace it with a screw. Frustrating to say the least and not a bit enough problem to do a return, but added a good 2 hours and frustration to an otherwise smooth build.Ver másVer menos

  Fantastic Small Case

  I have been desperately looking for a great small case for my sister. Sure there are some great ones out there for Mini ITX; however, both of the ones I tried got really hot, like almost a space heater hot. And both had really poor air flow. Being too hot isn't good so I decided to go Micro ATX and I am so happy I did. I paired this case with MSI MAG B550M Mortar MAX Wi-Fi Gaming Motherboard, AMD Ryzen 9 5900X 12-core, 24-Thread Unlocked Desktop Processor, Be Quiet 240 AIO. These parts may be a bit older; however, for the price my sis got a fast PC she can enjoy for years without it taking up a lot of space.Ver másVer menos
