Does everything a case NEEDS to do... mostly getting that air in and keeping things cool. The built in arm for GPU support is VERY NICE! The only folks that might find a problem with this is someone loading up on a pile of 2.5 inch SSD's because one of the cages for it is directly in the way of the PSU cables for a regular "wires out the back" PSU's. otherwise... it's got air flow in all the right ways! But yea, so far getting great thermals. I have built loads of PC's and this one is not fairly easy to use and access. It is big and will take more more space than usual. Case quality is high, b

This case is amazing for airflow, plenty of room for large components like long GPUs. Extremely easy to build in and cable manage. Really good build quality and it looks nice too. Good value for the money when compared to the cases it's competing against. I think this is the largest case I've purchased so make sure to check the space you have available to place it to make sure it will fit on/under your desk.I've set the case fans to cap out at 60% when in game and it still keeps my GPU (7900xtx) extremely cool and stays quiet.Only negative in my mind was I pre-ordered this after seeing the Gam
Nice air flow case that is decent in size which is great. I grew frustrated with the included fan controller. Motherboard wouldn’t detect any fan was even connected to the header. Ended up connecting the fan connectors directly to the system fan headers on my motherboard which solved the issue.
This thing is really big but i love the fans the size really matters and the design has plenty of space for changes to the build in the future i really think its not the prettiest design on the market but i can say it makes up for it in utility and that personally matters more
Very easy to install everything into the case. The massive fans help keep the case and the components nice a cool. Highly recommend if you have the space for the beefy size of the case.
This case feels both massive and surprisingly constrained at the same time. On one hand, it is huge at 80 liters in volume and comes equipped with three massive pre-installed fans that move an incredible amount of air—so much so that it actually sways the curtains behind my PC! Visually, I love the rugged, industrial aesthetic behind those front grills.The overall build experience was great: cable management routing and installation were very straightforward, and the flexible panel design allows you to easily pop off various covers and panels to move things around.However, despite its massive
Was very excited to get this case, but received an damaged unit----The air ramp and HDD bay were boucing around within the case and caused many visible scratches and dents. And one of the side panel latch is bent outward.If this unit is brand new, then Cooler Master did a terrible packaging job. What a shame it has to go back.Regarding the case itself,The Good: 1. A lot of clearance for CPU tower cooler and GPU; 2. Included 220mm/180mm fans are made of high quality sturdy plastic; 3. Front cover and filter can be easily removed.The Bad: 1. Very little space for cable management and SATA drives
Normally, I rather smaller cases, but with new technologies where 2 x GPU's are becoming a norm again, a case like this is almost a necessity. It's big, but it has a reason for its heft and isn't big for nothing. The Case itself is very sturdily built. While I won't test it, I am confident this can take a fall, and damage the floor instead, lol! All jokes aside, its very well build without being too heavy. I like the front grill design. It just gives that rugged look, and allows it to fit in with living room decor without standing out.The interior is very spacious, with large included fans in
