Details
The A45 Open Frame ITX Case, designed by Monster Studio, is a precision-engineered solution for minimalist small form factor builds that demand both performance and structural integrity. Built from solid 10mm CNC-machined aluminum with a sandblasted anodized finish, the A45 delivers exceptional rigidity while maintaining a clean, industrial open-air aesthetic. Now featuring an integrated GPU protector as standard, it provides added stability and security without compromising its minimal design.
Unlike traditional enclosed cases, the A45’s open-air architecture maximizes unrestricted airflow, helping components run cooler while showcasing your hardware in full view. The thick aluminum construction eliminates flex commonly found in lightweight open frame designs, making it a reliable platform for long-term builds.
Designed with flexibility in mind, the A45 supports ITX motherboards, ATX or SFX power supplies, and full-length GPUs. It also offers broad cooling compatibility, supporting downdraft and tower air coolers as well as AIO radiators ranging from 120mm up to 420mm (with optional accessories). A vertical GPU configuration is supported using a recommended 11–15cm PCIe riser cable, allowing for a clean and modern layout.
Storage support includes up to two 2.5” or 3.5” drives, and the included radiator mounting bracket makes AIO installation straightforward. Every aspect of the A45 is engineered for builders who want a durable, high-performance open frame chassis with a refined, minimal footprint.
If you’re building a clean, high-airflow SFF system with uncompromising structural quality, the A45 delivers exactly that.
