Minimal Design,Multiple Styles
The B4-mATX offers a clean mesh panel for an airflow-focused look or a real wood panel for a warmer, refined setup. Both support front-to-back airflow, balancing cooling performance with a streamlined exterior.
Vertical Mode,Maximized Desk Space
The vertical layout improves desk space efficiency by up to 30%. Integrated rear feet allow quick and easy switching between different usage modes.
Note: In vertical mode, the rear clearance for the connector and cable routing is 52mm in total. Please ensure your HDMI / DP cable fits within this space.
Rotatable AC Power Connector
(Rotate outward)
(Rotate inward)
Designed for both horizontal and vertical configurations, the rotatable AC inlet adapts to your setup. Face it outward for convenient cable access, or rotate it inward in vertical mode to avoid clearance limitations.
Note: The power cable is pre-secured to prevent rubbing against the chassis when rotated. Leave the cable tie in place and position the cable before assembly.
