Description

GENESIS Irid 503 Micro Tower Black is a compact PC case designed for efficient airflow and flexible hardware configuration. The front panel is perforated for ventilation while the side panel is tempered glass with a black print that conceals internal perforations. The case body is made of black steel and combines a small footprint with support for multiple storage drives, fans and a 240 mm liquid cooler.

Advantages

The Irid 503 includes two silent 120 mm fans preinstalled and supports two additional fans, improving internal airflow. It features tool-free slot-in drive trays for up to three 2.5" SSDs and two 3.5" HDDs, plus easy cable management with space behind the motherboard tray and rubber grommets. The top I/O panel provides three ports including one USB 3.0 and two audio jacks. The case accepts Mini-ITX and Micro-ATX motherboards and can accommodate a liquid cooler up to 240 mm.
