    • Great Case!
Size: Air 903 Max Black
Pros: Super easy to build in. HDD Cage comes out with just thumb screws giving you the whole basement for power cable management. Tons of clearance in the front and top for any radiator with 120mm or 140mm fans. My Xfx Speedster Swft 319 rx6800 graphics card fits with tons of room to spare. Four 140mm fans are included (3aRGB, 1 black) as is a control hub. Magnetic dust screens are awesome and air flow is exceptional. Both the glass and metal sides attach with captured thumb screws so you can't lose them. All of the expansion slots in the back have thumb screws as well. Build quality and finishes are above average for the price range. Cons: Included fans are on the louder side, but tolerable if you set up a custom fan curve. Only average room for cable management in the back. Power and front I/O are on the side that you would normally face away from you. Definitely not deal breakers though. Bottom Line: Definitely the budget king! It has everything most people need, tons of space, easy to build in, excellent airflow, 4 included fans, and it looks good. You can't do better without spending twice as much. ... show more

    • Great case but terrible coil whine from the exhaust
Size: Air 903 Max Black
The case itself is great to build in, with plenty of space and openings to route cables; I had no issues getting anything to reach its intended destination. Excellent airflow/thermal performance - the pre-installed fans move a lot of air, and the ARGB is nice. The included fan hub worked perfectly with my B850 Tomahawk motherboard. Chief Downside: The exhaust fan has very noticeable coil whine, and can't be set above 20% speed without driving me crazy; it's like having a dentist's drill whirring right next to me. I detached this fan from the hub to run it at a constant low speed, thus allowing the intake fans (which do not have any coil whine) to run an actual curve. I will replace the exhaust fan at some point; you should budget the cost of a new fan into the cost of this case, imo. ... show more

    • Excellent case, a bit loud but has great features.
Size: Air 903 Max Black
I love how this looks and how easy cable management was. Having a PSU shroud was amazing for hiding excess cable. The front fans are powerful, but a little loud when they ramp up. The RGB is nice and functions well. It fits my large GPU just fine, and had plenty of space for AIO coolers. This is one of the easiest cases I have built in and I would gladly buy this again for future builds ... show more

    • Sleek Design and Excellent Airflow Make This Case a Winner
Size: Air 903 Max Black
This computer case really caught my eye with its modern styling, and I was even more impressed when I finally built my new desktop using it. One of the standout features is definitely how much air this case can move. Keeping the components cool is crucial for performance and longevity, and this case seems to do an excellent job of promoting airflow throughout the system. The inclusion of RGB lighted fans is also a fantastic touch. They add a vibrant and customizable aesthetic to the build, allowing for a personalized look that's visually appealing. Furthermore, the case comes equipped with all the essential cables needed for setup, which is a thoughtful detail that simplifies the building process. For anyone who appreciates a clean and organized interior, this case shines in its cable management design. The strategically placed pathways make it easy to route and conceal cables, resulting in a tidy build that not only looks better but can also contribute to better airflow. The user-friendly design facilitates easy access to the internal components by making opening the case straightforward. Pros: The product has the ability to move a lot of air. Looks great. Low noise. The cable management is excellent. I am extremely satisfied with my purchase. Cons: None I found. Overall, this computer case offers a winning combination of attractive design and practical functionality. The excellent airflow, coupled with the stylish RGB fans and thoughtful cable management, makes it a fantastic choice for any PC builder. I am thrilled with this purchase and would highly recommend it to others looking for a high-quality case. ... show more

    • Decent for the price
Size: Air 903 Max Black
Pretty good case, I like the cable management and the airflow is good. The fans are very pretty with the aRGB lights. The thumb screws are pretty wonky though, they don’t screw in very easily. The panels for the graphics card in the back feel pretty cheap as well. Overall a good case for the money with a few minor annoyances. ... show more

    • Fantastic.
Size: Air 903 Max Black
Awesome case. Cable management is soooo easy, it breathes well and stays cool, fans are relatively quiet, the RGB is nice, installation of all my components was really easy, and you can buy 3 more of these exact fans to put in on top for extra ventilation and RGB for only like $30. 10/10 overall - one of the nicest cases I’ve ever used. ... show more

    • amazing case for the price
Size: Air 903 Max Black
Simply put this is an amazing case for the price. I do wish their was software for the RGB fans but I dont mind at all since it comes with a full USB fan hub that makes connecting all the fans so easy and helpful Normally a hub like the one in this case would cost an extra 30 to 50 bucks and you would have to find a way to stuff it inside but here this is awesome. It fits a standard ATX with no issues and has space to move things around The one downside is one of the MB standoff does not work for putting my MB on it. I dont mind since it is only one and 4 other stand offs fit just fine also It could be my MB being slightly different. This is not a big deal since the middle one and 4 others fit just fine. The look is simple and without it being too gamer like and you can use it for so many other things too. ... show more

    • Roomy case. Great air flow.
Size: Air 903 Max Black
Great case. Plenty of room. Instructions were not super clear on how to connect the 4 rgb fans but I figured it out.
