Things to Consider

The case is large (285×517×490mm) and heavy (about 14kg), so ensure your desk or floor space can accommodate it. While it supports EEB motherboards, most users will use ATX or Micro-ATX, and the EEB support is limited to specific workstation boards. The tempered glass panels show fingerprints easily and require regular cleaning. Additionally, the price point is slightly higher than comparable full towers without RGB controllers, but the build quality and features justify the cost.
