Product information

Description

Signum 300 Solid is a compact mid-tower PC case designed to provide effective airflow and practical component compatibility. The case features a mesh front panel, multiple fan mounts and support for tall CPU coolers and long graphics cards. It ships with one Stratus 120 PWM fan and offers drive bays for a combination of 3.5-inch and 2.5-inch storage devices.

Advantages

The mesh front and numerous fan mounts enable strong front-to-back airflow while retaining a compact footprint. Compatibility with a 350 mm long graphics card and a tall CPU cooler allows installation of high-performance components without compromise. Included Stratus 120 PWM fan provides quiet, controllable cooling out of the box. Multiple drive bay configurations support both larger HDDs and several smaller SSDs.

Key specifications

  • Form factor: compact mid-tower
  • Maximum GPU length: 350 mm
  • CPU cooler clearance: supports tall air coolers
  • Fan support: up to 8 fans; includes one Stratus 120 PWM
  • Storage bays: 2 × 3.5" + 2 × 2.5" (or up to 4 × 2.5")
  • Front panel: mesh for improved airflow

How to use

Install the motherboard on the standoffs, then mount the CPU cooler making sure there is enough clearance from the side panel and other components. Fit the graphics card up to 350 mm long into the PCIe slot and secure it to the chassis. Configure fans according to your cooling needs and connect the included Stratus 120 PWM to a PWM header for automatic speed control. Install storage drives in the appropriate bays and manage cables behind the motherboard tray to maintain airflow.

Recommendations

For optimal airflow keep intake and exhaust fan configurations balanced, use the included Stratus 120 PWM on a PWM header for lower noise at idle, and route cables neatly to preserve unobstructed air paths. Verify GPU and cooler dimensions before purchase to ensure compatibility with the 350 mm GPU clearance and tall cooler support.
