Product information

Description

ENDORFY Signum 300 Solid is a black tower PC case designed for effective airflow and practical component accommodation. The case supports ATX, Micro-ATX and Mini-ITX motherboards, fits a 350 mm long graphics card and a tall CPU cooler, and provides mounting space for up to eight fans. It includes one Stratus 120 PWM fan and supports radiators in 120 mm, 240 mm and 360 mm configurations. Storage options include two 3.5-inch bays and two 2.5-inch bays. Exterior dimensions are approximately 413 mm (W) x 205 mm (D) x 447 mm (H).

Advantages

The Signum 300 Solid offers a mesh front panel and multiple fan mounts to maximise airflow in a compact tower form factor, while the included Stratus 120 PWM fan provides quiet, PWM-controlled cooling with a long-life fluid dynamic bearing. The interior layout permits installation of long GPUs alongside substantial cooling solutions, and the combination of 3.5" and 2.5" drive bays gives flexible storage configurations.

Suitable for

Gaming builds with a single long graphics card (up to 350 mm)
Home or office PCs requiring good airflow and quiet cooling
Systems using ATX, Micro-ATX or Mini-ITX motherboards
Builds needing multiple storage drives (2x 3.5" + 2x 2.5" or 4x 2.5")

Key specifications

Form factor: Tower
Supported motherboards: ATX, Micro-ATX, Mini-ITX
Included fans: 1 × 120 mm Stratus 120 PWM (rear)
Maximum GPU length: 350 mm
Drive bays: 2 × 3.5", 2 × 2.5"
Radiator support: 120 mm, 240 mm, 360 mm (depending on configuration)
Front panel: mesh for improved airflow
External dimensions (approx.): 413 × 205 × 447 mm (W × D × H)
Colour: Black

How to use

Install the compatible motherboard (ATX/Micro-ATX/Mini-ITX) into the standoffs, mount the power supply in the designated compartment, and secure storage drives into the 3.5" or 2.5" bays. Fit the graphics card up to 350 mm in length and attach CPU cooler and radiators according to available clearance. Connect the included Stratus 120 PWM fan to a PWM-capable header on the motherboard to enable automatic speed control. Use the mesh front and additional fan mounts to configure intake and exhaust fans for optimal airflow.

Usage recommendations

For balanced cooling and low noise, use the Stratus 120 PWM as an exhaust fan and add at least one intake fan at the front. When installing radiators, check clearance against GPU length and CPU cooler height; route cables cleanly to maintain unobstructed airflow through the mesh front panel.
