CORSAIR Crystal Series 680X RGB Case

This case is an excellent example of a unit likely designed by someone who has never built a computer. The case has a removable fan mount panel in front. That is an awesome idea, but the panel isn't big enough to install 3 140mm fans. The mounting hole pattern appears to be designed with 140's in mind, but only 2 can actually be installed at once. The case has a removable fan mount in the top. This fits Corsair's 100i and 115i perfectly which is great. However, they recessed the mount too far down which can cause fitment issues with some motherboards. Push+pull fan setups on those water cooling kits are not possible. Btw, the 115i does have clearance issues with the front 3 fans. The 115i may also put stress on boards that have the additional 12v input at the top (as is my case). The case has an alternate (vertical) graphics card mount location. This is awesome as it can be vital for the fitment of some large cards on some motherboards. This said, neither the website nor the manual make any recommendation for PCI-E extension cables. Additionally, there isn't any way to stabilize a card that is mounted in this fashion. The card's only support will be the PCI mount bracket. This allows a significant amount of movement and stress to be put on the card. Lastly, the mount puts the card's face up against the glass panel which significantly restricts airflow. (Btw, the 4000x does this too, but there is almost twice as much room left for airflow.) A glass or acrylic panel with fan mount holes could have allowed fresh air into the vertical GPU mount (or allowed exhaust out of the horizontal mount). Instead, the card is so close to the panel that airflow is restricted. The back area allows mounting of up to 6 hard drives which is awesome. This said the front panel doesn't have openings to allow cooling air in and there isn't anywhere to mount a fan for drive cooling. The intent may have been to use the power supply's fan to move the air, but many PSUs don't run their fans unless needed. Drive temperatures often approach or surpass operating limits. There's actually a perfect place for a 92mm fan in the front of the chassis, but the plastic bezel is solid and prevents air intake. Btw, the option to easily install drives from the outside like the 280x is now gone. There are two fans mounts in the bottom. Shifting these to the left side of the case could have allowed fresh air to be pushed into the graphics card, or allowed efficient extraction of hot GPU exhaust. It's a nice, big case. This said several panels will have to be left off, modified, or replaced with custom options on my build. I'll need to design 3D printed graphics card mounting components as well as a 92mm fan mount. I would not buy this case again if I had the choice. It is a disappointment.
