This case is very affordable, but still manages to hit pretty much all of the major points for being a great case. It has tons of room inside for mounting a GPU, even fitting a 7900 XT with it's huge mounting z-bracket. In terms of space just be careful with 140mm-fan top mounted liquid cooler radiators. There is only about 55mm of clearance before the vram heatsink and a thicker cooler like the 280mm Arctic Liquid Freezer will get inside the case but be unable to line up with the screw holes. Just use a 120mm-fan based radiator or front mount for AIOs. The case comes with plenty of extra screws and the rear slots for the GPU mount are thumb screwed in and not disposable which is a good sign. The stock PWM fans seem nice and are plenty quiet. The front fans come linked together and so they only need one header to plug into the motherboard. If you buy the 903 base you can move the rear mounted fan to the front to have 3 matching intake fans and then buy a new rear exhaust fan to mount. Cable management was very easy with the included raceway and the many holes for routing cables. The case seems stable and I only noticed the slightest deformation when torqing screws. Seems like a great case.

This is one of the best cases I've owned. It is incredibly easy to build in and the 3 140mm PWM fans included also make it worth the price. Plenty of room for large GPU's and radiators. Highly recommended for any builder.

I loved the overall design, feel, and functionality of the case. It has room for many fans and AIOs and fits most coolers with plenty of room to spare. The cable management is beautiful with this case and has tie-downs in the the right places. Overall, it’s an amazing case and I’d definitely recommend to anybody.

Better than my old corsair case for way less. Easy cable management built in. Enough space for modern gpus. Easy to clean (and access) dust filters. Fans push decent air but are still quiet.

Great case for the money, good storage, easy access, only complaint is 90* sata cables can't be used. Included fans work well fits my E-ATX dual cpu motherboard with ease

I was shocked at how premium this case felt for the price. It’s well engineered and the fans that came with it are large which surprised me because I overlooked the fact that they even came with them. The addition of magnetic dust panels is genius since they can be removed quickly for cleaning. PC parts also have more than enough space to fit inside the case and the glass side gives you a perfect view of your internals. It’s a beautiful case that performs well.

I like the price and actually the metal is not flimsy and super thin; it is a nice gauge of steel and is quite sturdy. Mine came with 3 140mm fans and power supply cover built in. Layout is OK with multiple SSD placement areas and one HDD placement area inside. Really wished the GLASS panel was on hinges but this is OK too. Real good bang for the buck. Only real drawback (if you can call it that) it that it is made in China.

I just finished my first PC Build in two decades, last build was Windows XP. I watched tons of youtube videos before deciding on parts. I wanted to build a sim racing/gaming PC to support triple 4k 42" monitors, so I knew it would need good airflow. I like others, like the look of a good PC, I was going to build in the HYTE Y60, I liked the look of that case and the fact you can put a screen inside. Then I thought to myself, once built it will be hidden behind the triple monitors and no-one including myself will see it. I could save some money and use on other parts, also I did not want any RGB, don't want any lights bouncing off the wall behind the triple set up. Mr Matt Lee from youtube, put me on to this case and boy this is a great case, thank you sir, you are a master with your builds. The cost of the case is insane for what you get, plenty of airflow, comes with 3 140mm fans. Plenty of room to build in, easily fit the RTX 4090, even came with a graphics card support stand. You can build with the graphics card vertically mounted if desired. I left mine traditionally mounted for better air flow. Cable management is great, comes with 3 Velcro straps down the center and plenty of cable ties. Enough room in the case to mount a fan hub and tidy cables up. 360 mm AIO fits perfectly in the top with enough room to get you hands in if you need to mess with the motherboard. One issue, the AIO screws that came with Kraken to mount the radiator from the top protrude enough so that the magnetic dust filter does not lay flat, would have been nice to have a fraction better counter sinking on the mounting rails. The case come with 3 140mm fans, 1 mounted as an exhaust and two in the front for intake. I put all three of the supplied case fans in the front for intake. You have to take the hard drive tray out to get the last screw in the bottom fan. Long story short, I ended up buying 3 better fans for the AIO, I used the original AIO fans to populate the rear exhaust and the bottom two of the case for a total of 9 fans. The only issue with this case and why I knocked a star off, and boy I debated the 4/5 stars because this is a really stupid reason to lose a star, and my ONLY complaint with this case. The case take two 120mm fans at the bottom above the PSU. This draws air through the bottom and pushes up through the GPU and out through rear and top radiator. As I had the spare fans from the AIO swap and it supports bottom case fans, I wanted to install them. The screws are top mounted and need to go all the way through the fan (1 inch) and into the case itself. These screws (8) need to be small and long, but they are not supplied at all. With this not using a normal mounting method, I would expect those 8 screws to come with the case. I reached out to their support and heard nothing. In the end I ordered "M3-0.5 Thread Size, 30 mm Length" from Amazon, ended up with a pack of 100 for $5. Only needed 8 but was cheaper than going to the hardware store and buying 8. You will need some washers as well, as the heads of the screws will go through the fan mounting holes. All worked out and now 9 fans including the 3 for the AIO. For the cost of this case and the great airflow, I can highly recommend this case.
