Inside the Silencio S600
Flipping open the door on the S600, we see the door internally is lined with a foam material which is designed to help with noise isolation and absorption. The door can be reversed to open the opposite direction should you have the need. Behind the door, we see a louvered and filtered air inlet design. Something less common these days is the 5.25" bay in place. The filter can be removed by pulling on the tab located at the top center of the intake opening.
Pulling the filter and we see that the front fan mounts are numbering two and a half. They are only ever so slightly slotted for fitment but not like we have seen and praised other chassis for doing. This limited movement means that you have a very little adjustment for how you want your fans positioned. Also of note are the flat spots at the top and bottom of the fan openings, which likely helps stiffen the steel, it may induce excess noise from the fans at higher speeds or loading conditions. I also see why the spec lists only dual-fan radiators in place upfront as the top half fan hole leads right into the 5.25" bay area.
Pulling the entire front panel and we can see it is retained by plastic pegs with a friction fit. The 5.25" bay can be removed, but still, I do not believe that a triple fan radiator will fit, but it is close, and with a little work, I think it could be done.
Puling the side panel, we see the main chamber. The main chamber is fairly wide open, with only the 5.25" bay cutting into the real estate of the inner chamber. The recess of the motherboard tray below the area in front of it now makes sense why EATX was not specified. The passthroughs are longer but not super wide, so larger bundles of cables may be a bit tricky. The CPU backplate cutout is large and sufficient for any CPU cooler and board combo I have seen to date.
Here we get a peek from the inside of the fan mounting and the front intake fan, which comes preinstalled. This is a 120mm based unit, which is PWM controlled. This is a welcome feature as it helps have a more controllable ramping, which can reduce noise. Also, the blade sweep is quite extreme.
Pulling the solid panel from the top reveals the top fan and radiator mounting. As you can see, it is quite open and should allow for some decent airflow. Included with the S600 was a magnetic fan filter, which we also showed installed here. This, of course, will allow a bit more system noise out from the chassis but also will allow heat to be exhausted or even air to be taken in, depending upon your configuration.
The PSU shroud area does what you would expect; it hides the PSU. It also has a bunch of holes that are used for mounting 2.5" drives via rubber isolation washers. Toward the front of the S600, we see the cutout in the PSU shroud, which serves to allow front-mounted radiators to pass into the PSU chamber.
