The FSP U691 full-tower PC case features three-sided 4 mm tempered glass panels—front, top, and left—mounted on a 0.8 mm SPCC steel frame, offering builders an unobstructed view of internal components while maintaining structural integrity. Steel mesh panels on the bottom and right sides, each equipped with removable dust filters, facilitate robust airflow management without compromising cleanliness. Measuring 451 × 258 × 568 mm (H × W × D), the chassis accommodates ATX, Micro-ATX, and Mini-ITX motherboards, and supports CPU coolers up to 180 mm in height and graphics cards up to 420 mm in length.
Internally, storage versatility is provided by a universal drive bay compatible with 3.5″ or 2.5″ drives, two dedicated 3.5″ bays, and three 2.5″ bays mounted behind the motherboard tray and on a removable HDD bracket to streamline cable management. Cooling options include a pre-installed 120 mm ARGB PWM fan at the rear, an ARGB light strip along the rear interior, space for up to four 120 mm or three 140 mm fans (or a 480 mm radiator) on the right side, and room for three 120 mm fans at the bottom. The front I/O panel, located on the right front foot, provides two USB-A 5 Gbps ports and one USB-C port. External panels secure with thumbscrews, and cable-routing channels are lined with rubber grommets to simplify installation and maintenance. The U691 is priced at approximately €129, positioning it competitively within the premium full-tower segment.
