- Pre-installed with three high-grade Momentum 14 LCP-blade fans utilizing fluid dynamic bearings
- Native chassis cutouts support reverse-connector motherboards alongside standard E-ATX platforms
- Dense bitumen sound-dampening material applied to panels effectively isolates operating noise
- Convenient modular architecture featuring a removable top radiator bracket and built-in GPU support
- Roof radiator mounting is constrained to a maximum of 280 mm, preventing top 360 mm AIO installations
- Reduced mechanical drive capacity compared to predecessor series with only two 3.5-inch bays
Overview
Heavy acoustic isolation layers bonded to structural steel define the desk integration and quiet-focused architecture of this mid-tower enclosure. Measuring 19.7 x 9.3 x 19.0 in (500 x 235 x 482 mm) with a net mass of 24.69 lbs (11.2 kg), the chassis utilizes a closed, gently curved front fascia paired with finely patterned aluminum side intake vents to intake ambient air while preventing direct acoustic paths. The left side features a light-tinted tempered glass panel that provides an unobstructed view into the primary build chamber, secured with tool-less ball-and-socket latching mechanisms that seat flush against vibration-damped steel contact points.
Internal tray engineering supports both traditional motherboards ranging from Mini-ITX to E-ATX (up to 10.91 in / 277 mm wide) and modern reverse-connector mainboards featuring underside power and header connections. Expansion clearance accommodates graphics cards up to 14.49 in (368 mm) in length, stabilized by an adjustable GPU support bracket designed to alleviate stress on PCIe sockets. Factory air delivery is managed by three front-mounted Momentum 14 PWM fans featuring liquid crystal polymer (LCP) blades and fluid dynamic bearings. These fans operate across a wide speed band of 350 to 1800 RPM, delivering up to 79.79 CFM per unit while maintaining a sound ceiling under 32 dBA under full load, complemented by an internal duct directing incoming air toward lower add-in cards.
Serviceability and assembly workflows are streamlined through a removable top radiator bracket that simplifies power connection routing, though liquid cooling headroom at the chassis roof is limited to 11.02 in (280 mm) radiators rather than 360 mm units. Front I/O integration delivers high-bandwidth external connectivity with a 20 Gbps USB 3.2 Gen 2×2 Type-C port alongside dual 5 Gbps USB Type-A ports and a combination audio jack. While multi-drive storage capacity is scaled back compared to older legacy enclosures, offering two universal 3.5-inch drive sleds and two dedicated 2.5-inch mounts, the combination of bitumen acoustic suppression and structural rigidity provides a reliable, whisper-quiet foundation for contemporary high-power builds.
