Product Showcase - Interior
So here we are at bottom side we can see the mounting area for the PSU, underneath it a ventilation mesh, which has dust protection with the help of a filter. Plenty of space, should you feel a need to install a 1200W (longer) PSU at one point in time, then that is certainly possible.
When we tilt the chassis backwards. Here's the bottom side showing the PSU ventilation mesh and dust filter, which is removable and thus easy to clean out.
And zooming in at the bottom here a little, we see that the chassis rests on rubber mounts, this prevents resonating noises coming from the PC, and makes your chassis more silent. BTW the four thumbscrews to your right holds the lower 3.5" drive bay in place.
Here we have the 5.25" optical drive locks, again a very simple mechanism. Once the DVD-ROM or whatever unit is inserted, line the screw holes with the tiny pins of these locks. Click down the clip and the entire device is secured. You just slide in the unit and click it secure. That's time saving stuff as it is tool free. Again one of the very simple yet very handy features this chassis has to offer. You can install up-to four 5.25" devices.
