A genuinely fantastic case, it's huge but is absolutely worth the price. It comes with 3x140mm stock intake fans and 1x120mm stock exhaust. It has open support on both the top and bottom radiator for up to 3x140mm fans respectively, is a dual chamber meaning cable management and clearance headroom is extremely easy. It's access and latching are also extremely friendly, featuring double take magnetic + non-detachable screws that are incredibly easy to use. If you want a good dual chamber large case for extra fan support or easier cable management, this would be my ultimate recommendation

The was an excellent purchase. This case exceeded my expectations. This case has plenty of room to install all of my components. I the airFLOW is superb! I use a large cpu cooler the Dark Rock Pro 5 which fit perfectly. The other fans that come with this case are very very quiet as well. I have zero complaints for the case.

If you're looking for a case with plenty of space and air flow, this is it. Having the option to install fans on the bottom is a great addition to create more air flow to keep all your parts cool and running efficiently. Has plenty of space to add any GPU you would want to install. Also, being a dual chamber case helps keep all your parts installation a breeze. And cable management is super easy with this case. I would definitely give this case an A+ since it exceeded all my expectations.
