It measures 415mm x 361mm x 193mm (H x L x W) and weighs just 2.7kg, which probably indicates the chassis uses rather thin steel sheets. There's support for one 5.25" drive, two 3.5" HDDs, three 2.5" SSDs, and an optional 120mm front fan.
Overall it's nothing special but at this price level you're unlikely to find much better.
With extremely compact footprint the SilentiumPC Brutus M10 Pure Black delivers ultimate value for money for system integrators and users on a budget.
Black coated interior is surprisingly spacious allowing to accommodate high-end components including full-size ATX motherboards, up to 320mm long graphics cards and up to 159mm high CPU coolers (like Fera 3 or Fortis 3). Apart from a single 5,25” drive bay there are spaces for three 2,5” drives and two 3,5” drives. Proper airflow is ensured by a single 80mm fan in the rear and large mesh dust filter in the front panel.
For added practicality the Brutus M10 features an front-mounted SD/microSD card reader and a two high-speed USB3.0 ports. The M10 also meets security requirements for office use as it is compatible with padlock and accessories compatible with Kensington lock.
