Pros & Cons

👎 Cons

  • The case's substantial dimensions (23.13" X 18.43" X 19.8") and weight (44.93 lbs) make it quite large and heavy, potentially challenging for transport or placement.
  • The emphasis on liquid cooling might suggest that an air-cooling setup may not fully utilize the case's design potential or aesthetic.
  • Only provides 4+1 drive bays, which might be limiting for users requiring extensive traditional HDD/SSD storage.
  • The high degree of customization for liquid cooling may lead to a more complex and time-consuming build process for some users.
  • The aesthetic of four large tempered glass panels might not appeal to users who prefer a more subdued or industrial design for their PC case.
