Entretien
Regular maintenance helps ensure optimal performance and extends the lifespan of your PC chassis.
Nettoyage du filtre à poussière
The Master M905 features filtered front, top, and base air intakes with pull-out dust filters. Regularly remove and clean these filters to prevent dust buildup inside the chassis, which can impede airflow and component cooling.
