The Define 7 is the latest pinnacle of the renowned Define series and sets a new standard for what you can expect from a mid-tower case in terms of modularity, flexibility, and user-friendliness. Swap out the ventilated panel to add three filtered fan positions. Remove the entire top for unobstructed building and routing. Three pre-installed Dynamic X2 GP-14 fans can be expanded to a total of nine fans. In the standard open layout, you'll find more than enough space for your custom water cooling with large reservoirs and radiators up to 420 mm. Switch to the storage layout and install up to 14 hard drives along with four dedicated SSD mounts.
