Now let’s take a look inside ISK 300-65. On Figures 5 and 6 you have an overall look from its interior. ISK 300-65 has a DC-DC converter on its bottom front part, in charge of converting the voltage provided by the external power adapter to the required voltages and cables. We will talk more about this converter later.

It comes with one 80 mm fan on its right side and a second fan can be installed by removing the black plastic cover located on the left-hand side of the fan in Figure 6. This is a “TriCool” fan, providing three different speeds (low, medium and high), configured through the switch available on the rear panel. Since there is a place for installing a second switch on the rear panel the second fan can be an identical “TriCool” fan. No information on the actual speeds, airflow or noise level is available.

In Figure 7, you can see the case with the top hardware removed. Of course this case will only hold mini-ITX motherboards. Because of its reduced height, it will only support CPU coolers with up to 2 ½” (65 mm) in height.

The single expansion card supported by this case is fastened to the case using a different mechanism, shown in Figure 8.
