Clearance is an important aspect of case design for the enthusiast as it establishes whether key components will be compatible with a chassis or not.
Starting with the CPU cooler clearance we can confidently report that big CPU coolers will fit inside Raven 4 without any obstruction problems. Installed within Raven 4 we have Noctua’s NH-U12P which is 158mm in height. Raven 4 can support coolers which are up to 165mm in height, so the popular options such as Noctua NH-D14 and Alpenfohn K2 and others will fit inside here without a problem.
Great CPU cooler clearance
Graphics card clearance is again, very good. For a single card configuration occupying the top PCI-E slot there is unlimited space for anything currently on the market but if you are opting for a dual card configuration then the upper HDD cage will need to be removed.
Good support for big graphics cards
In terms of water-cooling support, Raven 4 does have some provision but it isn't really designed for this purpose. There is obviously space for a 120mm radiator where the rear exhaust would mount. SilverStone have enabled the front cooling fans to be swapped out so that there are mounting spots for 3x120mm which allows radiators to fit but sadly the front HDD cages will have to be removed and be absent and the default airflow will be replaced with airflow from the cooling fans attached to the radiator.
Behind the motherboard tray there is copious amounts of clearance for good cable management practises. Due to tray being on the alternate side and our ruler not having measurements printed on its flipside we had to shoot this upside down! But as you can see, there is roughly 2.5cm of clearance to arrange cables.
