MSI has released the MEG EM9, an open-frame chassis built specifically for PC testing and thermal evaluation. This platform matters to builders and reviewers who need to swap components quickly without the constraints of a closed case. It removes the guesswork from hardware validation by exposing the system for direct airflow and easy access.
Open-frame chassis supports E-ATX boards and 420mm liquid cooling radiators
The chassis is designed as a flexible testing bench rather than a permanent desktop enclosure. It accommodates motherboard form factors ranging from Mini-ITX up to E-ATX. This wide range allows users to test everything from compact boards to large workstation layouts on the same frame.
Specifications
- Motherboard Support: Mini-ITX to E-ATX
- Radiator Support: Up to 420mm
- Storage: 2x 2.5-inch drive bays
- Fan Support: 120mm or 140mm top slot
- Back-Connector Compatibility: Yes
Thermal management is a core feature of the MEG EM9 design. The frame supports radiators up to 420mm in length for high-performance liquid cooling. It also includes a dedicated top slot for 120mm or 140mm case fans to assist with exhaust.
Storage and connectivity options are kept minimal to prioritize airflow and component access. The unit provides two bays for 2.5-inch drives. It is also compatible with back-connector motherboards, which simplifies cable routing during testing phases.
The MEG EM9 is available for pre-order in Taiwan at a price of 2590 TWD (around $82.05). MSI expects to ship the units to customers in late October. This pricing makes the testing platform accessible for individual enthusiasts and small labs.
The MEG EM9 confirms MSI's commitment to providing specialized tools for hardware validation. The open design and broad motherboard support create a reliable environment for thermal and performance testing. Buyers in Taiwan can secure their units through the pre-order channel starting now.
