SilentiumPC announced the Gladius M20 Pure Black, a new high-value ATX mid-tower case. Made with SECC steel and ABS plastic, the case is built with a design focus on low-noise, although it doesn't offer any active noise dampening material. Fan vents are kept to a minimum, and covered with dust filters, the side-panel is opaque, and most cutouts are valved with rubber grommets, or dust filters.

Measuring 197 mm x 465 mm x 440 mm (WxDxH), and dry-weighing in at 4.45 kg, the Gladius M20 Pure Black, seats ATX, micro-ATX, and mini-ITX motherboards. It offers one each of 5.25-inch and 3.5-inch exposed drive bays, from which the 3.5-inch bay converts into two discrete 2.5-inch ones; and a drive-cage, which holds four 3.5-inch drives, in addition to a 2.5-inch one. The motherboard tray offers room for CPU coolers as tall as 158 mm, and add-on cards as long as 400 mm. Ventilation includes two 120 mm front intakes, and one 120 mm rear exhaust. Front panel features include a "smartphone tray," two USB 3.0 ports, and HDA audio jacks.
