https://www.techpowerup.com/264063/fractal-design-announces-the-define-series-7-7-xl-chassis Featuring the most comprehensive refinement of design elements yet, the Define 7 brings a new body to the long established Define series while staying true to its heritage as a solid platform for the silent PC.
Always pushing boundaries, Fractal product developers added loads of new features to ensure that the 7 series is the most capable and cohesive Define range ever released. Thanks to an adaptable dual-layout interior, the Define 7 can easily accommodate motherboards all the way up to 285 mm E-ATX, extensive storage arrays with up to 14 HDDs, 4 SSDs and an ODD bay, and robust cooling with a 420 mm radiator and up to nine fans. Versatile new multi-brackets allow you to convert any unused fan position to an HDD, SSD or pump mount.
