  • A solid case -feature packed
Style: Air 903 Max Color: Black
I was impressed by the build quality at this price point. The ATX mid tower is spacious and well thought out. Special kudos for the built-in fan wiring hub which made adding a 4th exhaust fan a breeze. The tinted tempered glass side panel looks great and highlights the RGB fan displays. An amazing amount of ventilation with the completely perforated front, bottom and back, with convenient EZ to remove filters. One across the entire top of the case and a small pull-out one at the bottom rear by the GPU. I can highly recommend this model. ... show more

  • Great Case!
Style: Air 903 Max Color: 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

  • Good Value
Style: Air 903 Max Color: Black
Looks good, the RGB is easy to control and has nice features, and offers plenty of space for cooling. The four included fans help keep my entire system running cool even when under stress. The build quality is good for the price and the packaged wiring system was well-organized. For those completing their first build, the mounting screws for the motherboard come in a package stored away in the hard drive space. ... show more

  • Amazing Value!
Style: Air 100 mATX Color: Black
I have not bought a new PC case in years. This was less money than I have paid in the past and has a lot more features. Hinged glass side panel, 4 nice ARGB fans, pre wired to an ARGB controller; nice cutouts around the motherboard for routing wires and make a nice clean build; shrouded power supply area. This is a really nice case! My only complaint is the motherboard standoffs anre cheap and were difficult to install and the screws for the standoffs were even worse. I actually broke one just screwing it in. So be careful mounting the motherboard if you buy this case. ... show more

  • Amazing & Budget Friendly!
Style: Air 100 mATX Color: Black
I purchased the style Air 100 mATX case. This case comes with 4 pre installed fans (ARGB). The lights can be connected to the motherboard or a button on the top of the case. Because of the way the wiring was set up I decided to connect the lights to the case's provided led button. It has many options and works just fine for my needs. The fans are quiet and strong! They provide substantial airflow throughout. The case comes with a swivel door that allows easy access- very convenient and attractive appearance for any build in my opinion. The dust cover designed for the top of the case does catch a significant amount of dust when used. You will want to remove the back panel occasionally to remove dust build up where your cable management is, though. Overall you really can't beat the quality for the price of this case. I've been using it for well over a year now (at the time of writing this review) and have no complaints whatsoever. If you're looking for a budget friendly but high quality option- this is your case! ... show more

  • This Case is a Steal for the Price
Style: Air 903 Max Color: Black
If you can get this case for around $75 or less, I think it is an absolute steal. I have done 3 builds in them and I have enjoyed it. I love the included 3 RGB fans and 1 non RGB fan, for a total of 4 included fans! For this price, it makes it an amazing option especially when trying to adhere to a certain budget. I love how the front is not blocked off by glass so hardware is able to breathe, and it makes maintenance cleaning very easy. It has 2 rubber gromets on the right side of the motherboard, and well placed cutouts at the bottom and top of the chassis, making cable management easy. Just be aware when purchasing it is on the larger side. when compared to other Mid Tower cases. All the fans that are included are routed into a pre installed fan and RGB hub on the back making plugging in other fans and RGB accessories much easier. Overall this case is awesome, you cannot really beat it at this price since, in my experience, it has zero compromises. ... show more
