Cooler Master Silencio 550 review - Product Showcase

At the rear side we can see a total of three grommet holes, partly for liquid-cooling tubing yet also can be used for frontpanel USB 3.0 connectors, CM supplies a cable that leads to your motherboard USB 3.0 connector.

The more modern motherboards now all have a standard USB 3.0 connector on the PCB, it is very good to see ODMs make a move to that connector, as typically wires coming out of the chassis towards the rear IO USB 3.0 connectors, and that simply does not look rather nice.

You get 7 PCI slots made available to you.

Both side panels are once again insulated with a noise dampening foam, vastly reducing noise levels. It really helps.

Along with the chassis also comes a box with additional components, brackets, a little speaker, screws, tie wraps, manual and tool less hinges for 3.5" SSD/HDDs.

And here's where we reach the inside of the chassis. There's surprisingly much space to work in, there's plenty  of clearance on all sides. Remember this is a mid-tower.

Nice to see that matte black design leads inwards as well, that will certainly make your computer components pop out a little better. At the bottom we see space for the power supply, make sure you have a PSU with nice lengthy cabling as you can route it behind the motherboard.
