The media could not be loaded. The Dual chambers of this case make building in it that much more convenient cause of how spacious it is inside. It can properly fit a few different motherboard sizes, including Mini-ITX, Micro-ATX, and ATX with some reporting E-ATX as well after removal of the cable management tray. A couple standoff screws I had to remove took some fiddling with a wrench but that's to be expected. The cable management is on another level, there are useful velcro straps in the rear chamber that go up and around the top of the case, with all of the case's front I/O Input cables and stock fans' cables routed through them already. The build quality of the case itself is awesome to behold, it reminds me of a fish-tank, but it's for your computer! It definitely has some heftiness to it, the tempered glass panels have a black border around 2/3rds of the panel, but it's pretty easy to get your fingerprints on them at one point before putting it all together, so have a lint-free micro-fiber cloth at the ready and maybe some Isopropyl alcohol. When it all comes together, an Intel i9-12900k sits around 35C at idle during the spring time thanks to the NZXT Kraken 360mm AIO liquid CPU cooler. The GIGABYTE Aorus GeForce RTX 5070 Master sits near 32C at idle with help from three 120mm bottom intake fans. I also ran a few recently released or demanding games at the highest settings possible at 1440p at a max of 165FPS to monitor how temps were: Marvel Rivals - Temps were under 58C and CPU temps hovered around 45 capping at 49C in the Practice Range area at high GPU/CPU loads. The Elder Scrolls IV Oblivion Remastered - GPU at 98% load and temps didn't exceed 58C while taking down the yellow team in the arena and traversing Cyrodiil. CPU temps were consistently under 55C as well. Throne and Liberty - CPU Temps hit 67C max during shader optimization and GPU was mostly around mid 50s, capping at 58C while running around in shapeshift form. CPU didn't exceed 58C during normal gameplay either. Call of Duty Warzone: CPU max temp was 62C and GPU's was 59C. God of War Ragnarok: GPU and CPU temps didn't go above 60C during multiple Valhalla runs. My one caveat with this case: The side panel can be tough to get properly seated after opening. The two glass panels meet and there's a bit of a gap, which is normal, especially since it comes shipped with a piece of cardboard between the two, but I noticed the gap was slightly bigger than when it shipped, and that the bottom circular shaped rubber notches weren't properly inserted. I think I ran into this issue during my first attempt to re-insert the panel cause I had the case vertical. I then turned it on the perforated mesh side of the case and figured out the method that worked for me to get the panel back in properly. Solution to re-insert glass side panel: I had to basically angle the tempered glass panel towards the bottom to fit the circular notches at the top correctly, then lower the panel to the bottom of those lower notches while pushing the top of the panel inwards so that the topmost spherical notches insert into the corresponding circular cutouts there. (Doing all this while avoiding leaving any fingerprints and smudges on the inside of the panel can be tough!) tldr: Great case to build with, display, and admire! One caveat: the glass side panel is a bit tough to re-insert.

Case arrived in perfect condition. Needed a bigger case for my 40 series graphics card and 360mm air water cooler. Personally i think the lian li cases are a little bit better. The lian li O11 full tower would be comparable to the h9 flow. But with this being almost 100 dollars cheaper it’s still a good option. The only thing that was an issue for me was the installation of my 40 series graphics card. I have a MSI 4070 ti one of the big triple fan graphics cards. I wasn’t able to install it the normal horizontal way i had to buy a vertical gpu holder kit. The issue comes from the cord management area there’s a big metal bar which seems to be standard with most next cases. Unfortunately it doesn’t look like it can be removed. This metal bar blocked the graphics card from completely going into the socket. With a shorter/smaller graphics card this wouldn’t be an issue but was for me sue to the length of the 40 series card. Personally I didn’t mind buying the vertical gpu kit as it seems to be much more sturdy then the little metal bracket that comes with your graphics card. If anyone is interested in the vertical gpu kit that i purchased its the (Cooler master vertical GPU holder kit V3 black). 45 bucks easy installation solid product highly recommended. TLDR Case arrived in perfect condition while there are better options out there for the price point this is a good option.

Amazing case. If you're looking for a beefy case with ample room. This is the case you need. I upgraded from a much smaller case, this is at least 1.75 times it's size. The increased airflow and venting are amazing. I did purchase a Arctic Liquid III cooler and upgraded that as well. I saw a significant decrease in running temp. At least a 30% decrease in temps on cpu on a heavy load. Looks amazing pictures don't do it justice. Very happy with my purchase and heavily suggesting this case to my friends wanting to move to PC.

Very impressed with this case. The layout is smart, and cable management was pretty straightforward. Glass panels give it a clean, modern look. Temps have stayed consistently low even under load. Overall, solid build and well thought-out design — would definitely recommend.

This case is so spacious and beautiful, makes your new pc a centerpiece of your room. You can ignore a cable management if you’re not great at it- you won’t see a mess left behind because all the wiring left behind a door in compartment that you not going to see again unless you’re upgrading or if there is a problem. Case is quite heavy because of tempered glass covers but it’s not a big deal. For portability you have your smart phones. In all white builds if you choose a white case it makes an excellent choice. Unfortunately it’s price goes up due to you know what so I’d say I got a great deal buying it for under $200. If you see one at lower price- do not think for too long. Now I tell you why I removed one star. Problem that I unfortunately have: rgb controller from NZXT. It came with 3 fans in the front and controller for RGB. It worked for an hour and then controller stopped controlling RGB lights on fan. The lights were out. It took me a couple hours to test it and troubleshoot the problem. Controller is dead. It passes power to the fans but not lighting RGB lights. Plugging them into another controller activates light. Unfortunately I had to spend almost 40 bucks to buy another one. And with current economic situation I’m happy that they have one in stock. I wonder if we even going to be able to buy these parts in near future. Cheers, hope you have enough information to make your choices.
