PC case ENDORFY Signum 300 ARGB Tower Black — ATX, tempered glass, ARGB lighting, supports GPU 350mm, CPU cooler height 161mm

ENDR0FY Signum 300 ARGB Tower Black is a compact mid-tower PC case with a tempered glass side panel that showcases internal components and ARGB lighting. The chassis supports Mini-ITX, Micro-ATX and ATX motherboards, accepts up to two 3.5" drives and two 2.5" drives (or four 2.5" drives), and accommodates long graphics cards up to 350 mm and tower-type CPU coolers. The case includes four Stratus 120 PWM ARGB fans and can hold up to eight fans in total for flexible cooling and lighting setups.

Advantages

The Signum 300 ARGB provides a clear view of internal hardware through a durable tempered glass side panel and comes preinstalled with four Stratus 120 PWM ARGB fans featuring fluid dynamic bearings and PWM control for quiet, efficient cooling. The interior layout supports multiple drive configurations and long GPUs while offering space for front or top radiators (supports 120, 240 and 360 mm front radiators). Front I/O includes USB 2.0 ports and the case is supplied in a black finish matching common system builds.

How to use

Install the chosen motherboard (Mini-ITX, Micro-ATX or ATX) on the standoffs, mount storage drives in the dedicated bays, and install the power supply in the PSU compartment. Fit the graphics card (up to 350 mm) and the tower cooler following the manufacturer’s instructions. Connect the preinstalled Stratus 120 PWM ARGB fans to the motherboard or a fan controller using the PWM and ARGB headers for speed and lighting control. Route cables behind the motherboard tray to maintain airflow and close the tempered glass side panel once installation is complete.

Recommendations

For balanced noise and cooling performance, configure fan curves in BIOS or a fan-control utility using PWM control. Use high-quality thermal paste for the CPU cooler installation and ensure front panel filters are cleaned periodically to maintain optimal airflow and component temperatures.
