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.

Nice case
This is a nice case with lots of room to install stuff. My ATX mother board fit just fine inside with a lot of extra room in the front area - lots of airflow capability as there is mesh in the front with the three RGB fans that came pre-installed. Material seems strong and case is well made and the large glass window is nice to see all inside. Do not get a RGB power supply as it is covered up with this case and you will not be able to see it. The top dust filter is magnetic and come off very easily, the bottom one is just held in by some fingers that stick out and seems very flimsy - not a huge issue. Top area has enough room to install a 360mm radiator for liquid cooling but if the tube ports are near the rear of the case, the rear case fan area is blocked by them. The area behind the mother board has room to route cables so they are partially hidden with many cable tie attachment points. Hard drives mount from the back side and are in the covered area where the PSU sits, SSD's have a mounting point on the top of the PSU cover.

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.

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.

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.

Nice Case with RGB for the price
Great looking case, especially when the fans are on and attached to an ARGB controller or capable motherboard. Good internal layout, and easy to work in. Ample cable management room behind the motherboard tray. And very good ventilation and airflow for the price.

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.
