The DS-M1 uses an ultra light, specially-made metal outer covering, while the DS-M2 features a highly rigid double-decked structural design. The inner layer of both cases utilizes the DS-M1’s ultra light outer covering, while the outer layer of each case is finished in a magnificent polished ebony coating with the added protection of reinforced fire retardant plastics. Apart from their sleek elegance and precision, the new cases also effectively dampen noise from radiating professional fans inside during operation. The layout of ports at the back of the frame has further been designed for user-friendliness, allowing even elementary DIY users to easily identify and plug in ports.
