    from completed build Aurora

    Breathtaking. This case has two front 200mm ARGB fans to keep the system cool, tempered glass everywhere, and loads of customization. The back side has panels that hide your cabling so you don't even need to use zip ties if you don't want to. Front I/O is quite generous as well with 4 USB 3.1 Gen 1 Type-A ports and 1 USB 3.1 Gen 2 Type-C port along with the typical headphone and microphone jacks.

    Was going to get a smaller NZXT H500 case, but decided to go for something bigger with better thermals. The dual intake fans sold it for me and the case looks amazing, and has amazing thermals and beautiful tempered glass panels all over. Expensive for a case though!

    One week in: Looks great and I can confirm latest ASUS Aura works with this case as my board has an ARGB port. Plenty of cable management options although I didn't to amazing AAA wiring. The graphics card at 11.5 inches forced me to remove the cable management bar so no GPU support bar for me sadly. That surprised me. It was touching the metal. If it wasn't removable I'd have been screwed. PSU and HDD shrouds give a very clean look. Easy wiring although I did get lazy as I wanted to play with the machine. Running it with the mesh default front panel for max airflow. If you want, it comes with a swappable glass panel you can install in the front. The SSD mounting peg system is great and it allows you to showcase your SSDs or simply hide them in the back. They almost lose a star for their instruction manual reading like it was written by aliens.

    Looks beautiful, great airflow, a panel on the back that lets you cover up any undesirable cable management, not hat you need it because cable management is a breeze on this case. I would recommend a Cooler Master MF140mm ARG fan tor replace the one in the back, because it is not RGB.

    I like this case but I wish I would have gone with a full tower for my first build. This was a pain in the *** to work in. Plus, I had issues with the 200 mm front case fans not spinning. I could spend some more time with my cable management as well, i just wanted to get it to post and make sure my first build was put together correctly.

    I love the size of this case. It has plenty of room to do whatever you want. There are lots of ways to rearrange it and customize for your needs. My one gripe with it is the back panel. With it being tempered glass, they have panels that are there to hide your cables. For me, it was tough enough getting the glass on with all of my wires. I had to discard these panels and just install the glass. I am also not using the supplied RGB controller. It requires SATA power and am using a Lighting Node Pro anyways. Not needed.

    I was struggling between choosing this recommended by Gamers' Nexus & Asus TUF chassis recommeded by KitGuru. Deciding factor is it's able to fit 3 140mm fronttake fans and its neutral colour and design.

    It could be better if it has :

    • slightly more room for EATX cable management without sacrificing vertical cover & grommets part in chassis

    • better clearance for top 420mm radiator AiO 140mm fans + 140mm rear exhaust fan

    • modular acrylic LED strips protector near the edges of chassis inwards for uniform lighting, or crystalized edges for G.Skill Royal series theme

    from completed build Noob build.

    I love this case. I bought the H500P and immediately ordered and upgraded to this H500M. GPU support bracket to prevent sagging and flexing. Cute ARGB control board on the PSU rear cable cover. 4 usb 3.0 and 1 usb 3.1 type c. Fits 360mm radiators top and front as well as custom liquid cooling options using pumps. Incredibly well thought out premium case.

    The tempered glass on the front, top and side are incredible. The tempered glass on the back is ok, seems gimmicky to me but for somebody who wants to display clean cable management it would be great.

    Cooler master ARGB is not particularly amazing so I wish Corsair would make QL Icue 200mm fans but that is me being picky and has nothing to do with the case.

    Overall this case is amazing and even the cooler master pre installed 200mm ARGB fans look great, I just prefer Corsair.

    from completed build Beast of an upgrade...

    I loved the original 500 range for the twin fan looks before buying this one. I'm really glad I got this 500m even though it's a little spendy for what it actually is at the end of the day. However, price aside it's a beautiful case and refined in it's design. They even give a box of screws with many left over as spares and for future use. Nice touch! Cable management is an absolute breeze even for a 1st time PC builder like me. I'll get some custom cable mods to make it all look even better soon although it does get a bit tight for space under those covers on the backside of the case. My only real complaint was that I could not connect the USB C on the front panel as the cable that is supplied with the case is pre-made and rather short. I'm not sure if it is just the combination of my MSI motherboard and the h500m but there is no way to make it reach without an extension cable. Apart from that relatively minor issue, the case is stunning, sturdy and quiet. It's very quiet and I like it!

    from completed build My ROG Gaming PC (2019)

    It is a very good case, probably the best there is for a gaming PC at the moment.

    Here I wrote why I chose it.

    There are three things that could have been better though:

    • cable management windows that are next to the motherboard and allow to hide the cables better are partially covered by E-ATX motherboard. Once the motherboard is installed, it is not possible to pass the cables through, they have to be passed in advance, but that would make the board installation much more difficult. Without doing it though it's quite difficult to install front cable cover (that also has mounts for SSDs). All it would take to avoid this problem would be to move the windows just 0.5-1cm (!) to the front of the case - it wouldn't require a bigger case, just a bit smaller front cable cover. In my case I simply didn't use front cable cover, as I don't have SSDs other than M2 stick plugged into the motherboard and cables look good anyway.
    • the PCI card slots window. It would be nice to have rotating slots window to install 2 GPUs vertically, as even though there is one vertical mounting slot, GPU overheats there as it's too close to the glass. You could use CM mounting bracket, but you wouldn't be able to mount the second card in this case (other than in the stock vertical slot where it overheats).
    • top fan grill is too narrow even for 120mm fans (see the top photo in the build - airflow would have been better if the grill was wider and only allowed mounting 3x120mm fans. I understand that CM wanted to have more generic grill design in case there are no fans on the top or if you use 140mm fans, but 1) you can only have 2 x 140mm fans, 3 x 120 makes more sense and 2) they could have designed the grill to look good without the fans and still allow more airflow with the fans. I was considering cutting the holes under the fans, but it's probably a micro-optimisation.
