Pros & Cons

👍 Pros

  • Offers recessed radiator/AIO/storage mounting, providing more internal space for long GPU cards.
  • Supports VGA card lengths up to 450mm (without reservoir) or 330mm (with reservoir), accommodating high-end graphics cards.
  • Includes a newly added cooling mounting bracket specifically for AIO/case fans, enhancing airflow and cooling solutions.
  • Provides extraordinary air flow to cool all latest core components, addressing thermal management for powerful builds.
  • Features rotatable PCI-E slots, allowing flexible vertical or horizontal GPU mounting for aesthetic preferences.
  • Equipped with strong, steady Core P6-like foot design, ensuring stable display for heavy builds.
  • Offers three-way placement layout (wall mount, vertical, horizontal) for versatile display and setup options.
  • This open-frame case provides excellent visibility of all internal components.

👎 Cons

  • The open frame design, while aesthetically pleasing, offers less protection from dust and ambient noise compared to enclosed cases.
  • The maximum VGA length supported varies depending on whether a reservoir is installed, requiring careful planning.
  • While a cooling mounting bracket is included, the case design may still rely heavily on external airflow due to its open nature.
  • The "strong steady feet" might add to the overall footprint of the case, potentially requiring more desk space.
  • The three-way placement layout, while versatile, still requires dedicated space for each orientation.
  • An E-ATX case can be large, potentially posing a challenge for those with limited space or who prefer compact builds.
  • A PCI-E riser cable is not explicitly stated to be included for vertical GPU mounting, which would be an additional purchase.
