The Define 7 XL sets a new standard for what you should expect from a full tower case in terms of modularity, flexibility and ease of use. With its dual-layout interior, industrial sound damping and massively versatile layout supporting the largest E-ATX and enterprise boards, multi-GPU setups, outlandish water loops, and almost two dozen storage devices (in Storage layout), you’ll be hard pressed to find a limit to what you can do with your build in the Define 7 XL.
