Cooler Master takes a different approach to the 100+ Euro silent chassis. While other manufacturers aim to offer flexibility between air flow and silence, the Silencio 650 offers an extensive feature set with a few unique aspects. The Aluminum front cover is something some may have come to expect from a silent case of this price class, but things like the SDHC card reader and fan controller are by no means standard. On top of that the unique system drive selector is something you will not find in any other silent cases, which makes the use of dual OS configuration possible without the need of partitioning a single drive. On top of that, the Silencio 650 manages to deliver a great assembly experience, plenty of space and good cable routing possibilities. At first sight, the Silencio 650 may not look like much, with other silent enclosures simply looking more menacing or "out there", but in terms of features, the case manages to impress and justify the price tag - even if it does not quite offer the flexibility between silence and air flow as other silent cases, while giving customers the possibility to grab the much cheaper 550D if those extras are unwanted.
