A closer look at the outside
In a nod to those of us who keep our PCs under our desks, the Silencio 652S sticks its front-panel I/O up top. The power and reset buttons are on the edge of the front bezel, though.
We've got four USB ports (two SuperSpeed and two regular), mic and headphone jacks, an SD card reader, and a Cooler Master logo that looks like it should light up but actually doesn't. The only LEDs are on the front panel. The power LED is embedded in the power button, and the storage activity LED sits just below it.
Here's the Silencio 652S with its top, side, and front vents laid bare. The top cover simply slides off, but the side cover is kept in place by a couple of screws. Undoing those requires removing the side panel.
As for the front door, a simple magnetic latch keeps it shut. The door can also be removed, but that involves taking off the entire front-panel assembly and pulling out the pegs that hold the hinges together. Honestly, I'm not sure why anyone would bother. The front door is one of the Silencio 652S's selling points, since it's lined with acoustic foam. Thanks to all the venting along the sides, I doubt it impedes cooling performance much, if at all.
Here's the acoustic foam that lines the front door. The foam spans the door's entire height, and it feels soft and rubbery. From what I can tell, it's about two millimeters thick.
In its default configuration, with two pre-installed 120-mm fans up front, the Silencio 652S directs intake airflow through a removable dust filter. The filter is kept in place by a single plastic latch at the top, so it's painless to pop off and vacuum (or shake off outside, if the wind is right).
The side panels are also lined with foam, but the foam here is about half as thick, and it's made of a different material. It feels a lot more rigid, and the texture isn't the same.
That completes our external tour. Read on for a look at the Silencio 652S from the inside.
