The top cover is made from a UV-stabilized ABS/polycarbonate blend. While tough, repeated exposure to direct sunlight (heating the surface to 70–80°C) followed by rapid cooling at night creates micro-fractures. Over months, these grow into visible cracks, usually starting near screw bosses or corners. We surveyed 50 ACM Satellite Pro 129 owners
