Introduction (Cont’d)

This case has one 120 mm fan on its top panel and it has room for you to install two more fans there if you want to. The top panel cover can be removed by unscrewing one thumbscrew available on the rear panel.

The panel containing USB ports and audio jacks is located on the top panel of this case and what is different here from other cases is that its cover uses a touch-activated motorized mechanism (you need to install an adapter on the main motherboard power connector to use this mechanism). This panel is flawless, as it has four USB ports, one FireWire port, one eSATA port, mic in and headphones jacks.

In Figure 9, you can see the bottom panel from this case. As you can see it has a washable dust filter there, located in front of an optional bottom 120 mm fan which doesn’t come with this case (more about this in the next page). The ventilation roles located on the left side of Figure 9 are for the power supply and this case has another washable dust filter there, accessible from inside the case (we will show this filter in the next page).

Finally we have the rear panel in Figure 10. On this case the power supply is located on the bottom part of the case instead of the top part. On the top part there are two holes for water-cooling systems and you can also see a rear 120 mm fan which comes with the case. This case has seven expansion slots like all traditional ATX cases. On the top part of the rear panel you can see two levers, one at each side. By pressing these levers you open the side panels.

Let’s see how Cosmos S looks like inside.
