Overview
- The Antec ST20M is a well-engineered mid-tower case that combines compact dimensions with practical build flexibility. The integrated 550W power supply with Active PFC eliminates the need for separate procurement, reducing setup complexity and cost for small business deployments and custom builds.
Designed for micro-ATX and ITX motherboards, this case accommodates modern graphics cards up to 265mm and CPU coolers up to 150mm, making it suitable for contemporary hardware configurations. The front-facing USB 3.0 port provides fast data transfer, while multiple drive bays support both 3.5" and 2.5" storage drives.
At just 275 x 180 x 352mm, the ST20M fits easily into space-constrained environments such as office desks or retail counters. The single 120mm rear fan provides adequate airflow for typical business workloads, whilst protection features including Over-Voltage, Short-Circuit, and Over-Power protection safeguard connected components.
