  • Very nice case, features, great value.
Style: Max Black with ARGB FAN
This is well thought out case with outstanding features for a great price. It has good airflow, plenty of room for easy assembly, 4 included fans with fan controller. Recommended.

  • Nice, spacious, airy case
Style: Max Black with ARGB FAN
Affordable, ships to Alaska, comes with four fans installed. This case provides plenty of air for a 7800x3d setup with Phantom Spirit 120, and 4070 S. Make sure to set the fan speed accordingly and you’ll have a very quiet setup that has no overheating issues. The only issue I had is the power button being close to one of the USB outlets. ... show more

  • Overall, really great case, fans need better Q&A, as I had 2 fans in parts in 2 of same case.
Style: Max Black with ARGB FAN
Overall, a great case, I have purchased 3 of them black in color, 1 X 903 base and 2 air 903 maxes', the fans could be a better quality, or get better Q&A as in two cases I have purchased 1 fan blade hub not engaged or clicked in to fan motor and fan frame, and I had the back fan blades/hub totally separated from the fan itself flopping around the case. Packing is a little better, box still looks like it went through a handler with anger issues maybe, not as bad as the last one, but all came with holes and the plastic film discolored and bubbled like the box got wet at one time in its life or really cheap cardboard. Montech, how bought you send me some 140mm Argb fan/s and rubber cable pass through grommet/gaskets to make up for it. LOL. But I still really like the case and for the price and so many boxes checked, over other cases, and it's just a fan. ... show more

  • EXCEEDED ALL EXPECTATIONS
Style: Base Black
Absolutely the best bang for the buck. I work for a computer company and have built hundreds of systems. I have tried many cases in this price range and am usually disappointed in the quality. This case is different. The case is solid and heavier then the cheap thin metal used in other cases in this price range. It has three fans included (2 in the front and 1 in the rear). It is closer to a full tower then a mid-tower in size. Cable management is easy and unlike most the top has enough opening to run the ATX 12 volt 2x4 connector. I like that the screws are individually packaged and labeled for purpose. The top of the case has two 3.0 USB connectors and one USB Type C connector. My choice for all future builds. ... show more

  • Premium quality at a budget price!
Style: Max White with ARGB FAN
Building with this case is a blessing. Comes with all screws, well packed separately. Cables pre-managed with magic tapes. Comes with a pre-installed fan hub and 140 fans. I do need to force a bit to align my mb with the screws, which could be that it is precisely assembled. it's a bit big but well justified by its support on E-ATX boards. ... show more

  • Best budget case on the market
Style: Max Black with ARGB FAN
Just did a simple build in one, great airflow, great cable management options, filtered intakes, 3 140mm ARGB fans, 1 140mm fan, fan controller included, dust filters super easy to remove and install, all for $70, you can't beat it. 10/10 will buy again for future builds.
