Great, well ventilated case for the price
Great case for the price, excellent ventilation which helps keep your temperature and noise levels down. Fit, finish, and materials are at as expected and assembly was easy with plenty of room and cable management features to keep your build neat.

Button selector can be used even if the board doesn't support the connector.
My son can't stop telling me how cool his case is... It is getting old but it is pretty damn cool. His board didn't support the color control but you can manually control it with a button. He likes the pulsing/breathing green. On the install side it only comes with those front fans so you will need a few more for the back and top. The installation was great and there is a ton of room. The case material is a bit thin (I can bend parts of it with my hands, however no complaints for the cost. Excellent case with nice lighting.

great case for a budget build gaming pc
got this case to use in a gaming pc and absolutely love it. Lots of room for cable management, great airflow. The fans are super quiet and the ARGB LEDs are very bright. I used a separate Razer Chroma ARGB Controller to control their colors very easily and the only issue i had was getting their plugs to fit into the controller because they are a bit chunky, but i use a modeling file to shave them down and they fit just fine. My brother is ordering one of these to transfer his current pc build into because he liked it so much.

Decent for the price.
I'd probably rate this a 3.5 if that were an option, decided to round up to 4. I got two of these on sale for about $65 each, if I had paid full retail ($115), I'd probably feel ripped off. Pros: Lots of space. The two builds I put in them were budget builds so the graphics cards (6600) are small and the processors (5600) are just using their stock coolers. I'm confident that the case is more than big enough to support the longest graphics cards and most if not all after-market CPU coolers. The stock fans are relatively quiet, provide decent airflow, and the RGB seems fine if you're into that sort of thing (I'm not but my kids love it). The case has very good airflow with all the space and mesh panels. The tempered glass looks nice and is reasonably thick. The case itself feels very solid, being mostly metal parts. Cons: The tempered glass panels have one side with screws, and the opposite side has a U-shaped piece of metal that slides around a thin piece of metal in the case in order to secure it. One of the U-shaped pieces of metal came bent, making it a pain to take off and line up the screws. Not a big enough deal for me to try and RMA it, but annoying none the less. The cases would be pretty loud if I had better components with bigger/louder fans in it, but that's just how it is for every case designed to maximize airflow as far as I'm aware, so that's not really a problem for this specific model - a tradeoff for the good airflow it offers rather than a true con. The mount for SSDs is directly above some of the back plugins for an ATX motherboard where you would plug in the sound, power button, etc., from the case into. This is why this case gets a 3.5 and a full review from me instead of just a "5/5 good case". The case has SO MUCH SPACE, and yet it felt so cramped when I was plugging those wires in. I removed the SSD when I did it of course, but then I had to bend some wires out of the way to get it back in. There's just no need for that, if that mount had just been an inch or two higher, which there is more than enough space for, or if it had been put somewhere else entirely, there'd be no issue. I had to use my drill to get out a couple of screws that were holding the drive bays in (which make the space for the power supply needlessly cramped, I'd probably be whining about that as well if I had to actually use the drive bays and leave them in), as well as one or two of the screws for the removable grates on the back to stick the video and wireless cards out of. To be fair, the screwdriver in my computer building kit is very thin and hard to get good torque on, if gremlins (AKA my kids) hadn't apparently lost all of my full-size cross point screwdrivers then the drill probably wouldn't have been needed. Overall, now that the builds are put together the cases are completely fine, but it was a bit annoying to build in and I'll probably go a different direction next time. The case had a lot of potential, I think if the space had been better-utilized it would have made a big difference.

Looks amazing
This case was perfect for my build and I think it is a solid case for the price. It has a magnetic dust filter on the top, it comes with 3 fans on the front, and it has a clip-on dust filter for the power supply on the bottom. When I got mine, the led part of the fans did not work but I had a feeling it was the motherboard so I got a new motherboard but did not plug in the led part of the fans because I did not want to take another chance. But overall this is a good case.

Good value
Great case, I have had it for 4 years now, I haven't had a problem with lack of space, poor cool cooling.

Great case!
This case looks great, and is made by a brand I've come to grow fond of. The main selling point for me on this case was the Mesh front. A lot of cases these days have gone the way of Glass fronts, and I hate that as there's heavily reduced airflow. This case has plenty of slots for extra fans, supports my 2080 Super and Aorus Elite x570 Mobo perfectly. It also has a few USB 3.0 slots on the front which come in handy. Overall I'm very happy with this purchase.

Great case, included RGB SATA adapter is a different story.
I got the case and set it up, and it's great, fits a full size ATX board perfect, has the PSU shroud, and holds two full size HDDs perfect, but the included SATA power system for RGB literally burned itself when I plugged it in. I opened it after it started to smoke to find that the 101 resistor right off the main power input had burned. Besides that, the entire package deal is great! The fans are relatively quiet, and my CPU is now 4 degrees cooler just due to the better cooling that comes with the case.

Buena opción
Buena relación calidad precio. Caja espaciosa con 4 ventiladores incluidos: los 3 delanteros son regulables y llevan iluminación RGB. El ruido es bastante bajo y el flujo de aire es bueno. Permite buena gestión del cableado y el lateral es de vidrio, no de plástico.

AMAZING
The case comes with wires, so you don’t need to buy wires for your pc, you’ll find the wires under the case from inside, and the case is not heavy but it’s a really big case, It’s amazing I recommend it

A great gaming RGB cabinet.
A good gaming cabinet, after all. Front 3-rgb, noiseless fans, at max. speed & one at the back side. Enough space for my rtx2070 graphics card(30 cm) Enough space to fit my cooler master liquid cooler at top. There is magnetic on top-outside, above cooler master, of cabinet, plastic mesh to prevent dust Fits well, my msi x299 motherboard. Side glass panel, ok to view. Good value for money. Best cabine for gamers. Ample space for motherboard, wiring, SMPS, etc. Fits 2-hdd & 3-ssd. No dvd space, as not being required, now. Below smps, outside cabinet, a fine plastic mesh, to prevent, dust n small insects.

Decent case, easy to assemble, no issues at all.
This is a really good case. The case was extremely easy to assemble since it has magnetic attachable filters and parts that you can just take off (as well as some large screws). Although it is quite pricy and only has a fairly simple design, the air flow is extremely good. The temperatures I get for my RTX 2060 super reach only up to 61 degrees Celsius on full load. Some people were complaining about the fans being loud, but my fans were actually very silent. The RGB looks beautiful, and I love the side panel. The only thing that I wish wasn’t there was the red “fragile” sticker since it makes the case seem a bit less appealing. Overall decent case, but is somewhat pricy.
