This is not a PC case. This is a palace.
This is not a PC case. This is a palace. With a good case, the magic is not that it is big and lights up. The magic is that it does not fight you. You remove a panel, and you can reach inside. You take out a bracket, and a path opens. You do not have to twist a PCIe cable into origami with your wrist. You do not have to pray that a screw does not fall into some black void. You do not have to remove three components just to reach the fourth. That is why building a PC can become an experience. It was not just a technical operation. For once, the hardware allowed me to think properly in space.

Perfect for watercooling
This is a full tower so is very large. The build quality is top of its class. My system is running: Corsair HX1000i PSU MSI Edge z790 Ti Max WiFi Core i7 13700kf 3x 120mm Reverse blade Lian Li TL LCD Fans (bottom) 3x 120mm Reverse blade Lian Li TL Fans (back-side) 2x 120mm Lian Li TL Fan (rear) (rear by I/O) 3x 140mm Lian Li TL Fans (on radiator at top) EKWB 420mm Performance Radiator EKWB D5 pump + 200ml reservoir EKWB Quantum Velocity2 CPU waterblock ASUS Tuf 3080 GPU 2x Lian Li Strimmer v2 gpu cable 1x Lian Li Strimmer 21pin ATX cable Cablemod EPU cable extensions 5x SSD 3x NVMe This gives you an idea of the huge amount of space inside the case. The Fans are attached to cages which can be removed as an entire unit (side, bottom and top). My fans and strimmers are running on 3 controllers highlighting how much cabling space is in the back. I also have a NZXT usb header expander which connects to Fans, strimmer and psu - again enough rear space for this also. The front I/O can be moved to various positions to allow for different case orientations. The motherboard can be adjusted up and down to allow the system to be laid out exactly how you wish. A vertical mount will not put the gpu too near the glass. The hot swap cages in the rear can be removed if you do not need them to create more space for cable management. I sometimes found that the rubber grommets were a little large which meant cabling could look a bit untidy. I've overclocked my gpu to within an inch of its silicon life and it runs a good 10 deg cooler than it did in its previous case (runs about 65-70deg under full load). The mere size of the case allows such efficient air flow that case temp does not rise when efficiently cooled. The internals have various straps which can be moved around inside the case. SSD drives can be mounted to a magnetic door which can be opened to allow access to the cabling. Noise levels will be entirely dependent upon which fans you use. The Lian Li ones are virtually silent even at high speeds due to them using fluid bearings. It was an incredibly easy case to build in. Speed of installation will be totally dependent upon the complexity of your build. Whilst this case is up there with the top end, I highly recommend it if your budget allows. It is pretty good value for money. Once your build is complete the front vertical bar can be removed allowing for uninterrupted view of your components. It comes with fantastic build components allowing for blank areas to be covered. It also comes with all your stand-offs and a nice plastic, compartmentalised box with plenty of extra screws. The RGB strip that runs vertically on the front-side of the case can either be controlled manually by a button on the case or by connecting the 5v (3pin) connector to an rgb header on you board. Be aware that this comes with 2 usb 3.0 cables to the front I/O so of your motherboard only has 1 USB 3.0 header you either A. Leave one unconnected (which means two usb ports on front I/O won't work or B. Buy a converter which will allow you to connect it to a USB 2.0 header on you motherboard. These can be picked up for a couple of pounds. This case was a dream to build in and will really give your PC a showcase feel due the two toughened glass panels at the front and side. If you wanted to add a small monitor inside to show system temps you could dominator very easily. Just be mindful that this case is big- I would recommend measuring your space first.

Great
It looks great and will be easy to build in. You have lots of room to be creative as well. I didn't keep the case because of the size of it. If you plan on going with a liquid cooled pc or going to slap loads of fans in it, get this case.

Lots of space
Great case, well built with lots of space. Only issue for me is the position of the I/O ports which can only be at the bottom of the case. I like my case I/O ports to either be at the top.

This is a vast case, that is well made and has excellent airflow.
I am concerned by the reviews saying that this case is cheaply made, as it is not. One negative review here refers to receiving it with the rear of the case damaged, and includes a picture of some case damage, that is not the rear of this case. someone else says you cannot fit two rear case fans. You can. I have attached a video of my case. I am running an Asus Rog Strix z790-f gaming wifi mobo, with a 13th gen i9 and the reason for my purchase, a very large RTX 5090 FE graphics card. I have used Coolermaster Halo2 fans. You can see my blinds moving in the video, that's how good the fans are. My PC is almost 3 feet away. My CPU never gets above 58 degrees.

Worth every penny
Really love this case. I can’t express how well designed this case is. Only caveat is that where the two glass pans meet there seems to be a little gap where dust can enter. I have needed to add duck tap over the gap to prevent dust from entering. Other than that really worth it. Please note that depending on what you have in the case and depending on if you want the double glass pans without the metal beam you may suffer with the same issue I have. Let alone I could be the only one with this design issue.

First class service
The case was delivered well packaged and on time. On opening the box the case was found, in good condition with all accessories inside box, as expected. The quality of the case was excellent, with plenty of space to build in and also looked good, better than I hope for. I highly recommend this case for doing a build as size, structure and layout inside it was really good, which will allow me to fit my components easily. The prompt delivery and condition of item makes it easy for me to recommending this seller.

Il est grand il est beau et efficace
Rien a dire, cest grand, il y a de la place, attention il faut commander des ventilateurs car ce n'est pas fournie avec, et ce n'est pas plus mal car les ventilateur intégré ne sont pas de grande qualité en général

Super amazing case, but the only problem is if you have a chunky GPU like 5080, will not fit with case holder you need to external holder or sag bracket
