Pros & Cons
👍 Pros
- Supports both vertical and horizontal motherboard orientations, offering flexibility for different build aesthetics and space requirements.
- Features a preinstalled large 200mm front fan and extensive fan/radiator support for exceptional cooling performance.
- Designed with an endless stackable capability, allowing for external modular upgrades and expanding system utility.
- Optimized for space management with a dual-chamber design, separating cooling/efficiency from PSU/drive bays.

👎 Cons
- While stackable, physically upgrading or rearranging stacked units could be cumbersome for some users.
- The dual-chamber design, while good for organization, might require more careful cable management to fully utilize.
- Clearance for CPU coolers, VGA length, and PSU length are specific, potentially limiting choice for oversized components.
- The extensive fan support requires purchasing additional fans for maximum cooling, as only one 200mm fan is preinstalled.
- The modularity might appeal more to enthusiasts than casual builders looking for a straightforward assembly process.
