Product Info

The Silencio S400 White Steel is part of Cooler Master's Silencio series, positioned as a mid-range silent case. It features steel construction with a white painted finish and a solid steel side panel for noise isolation. Standard cooling includes one 140mm front fan and one 120mm rear fan, with room for additional 140mm fans at the top. Priced around ¥19,000, it offers good value for a quiet chassis with solid build quality.

Best Use Cases

Office workers who demand silence: The steel dampening panel and soundproof covers make it perfect for noise-sensitive environments. PC builders wanting a compact yet capable system: Supports large GPUs and tall CPU coolers, so you can build a quiet gaming PC without sacrificing performance. * Budget-conscious users seeking a quiet case: Compared to other options in the same price range, the Silencio S400 delivers excellent sound damping without extra cost.

Things to Consider

The steel side panel means no window for viewing internal components, so it's not ideal for RGB showcases. The top panel includes a sound-dampening cover; removing it is necessary for better exhaust with high-TDP parts. The case ships with only one front 140mm fan, so additional fans are recommended for optimal cooling. Also, the front intake relies on side gaps from the steel door, which may not be as effective as mesh panels for airflow.
