The side panels look nice and measure about 56x57cm, which is almost like four 17’’ displays.

Both side panels are opened via handles on the rear panel. 

The side panels need not be removed as they’re attached to the chassis by hinges. If the panels are getting in the way while mounting components, for instance, a slight push upwards will make them fall off the hinges.

Once the panels are closed they’re quite firm as sharp metal parts (picture below) hold it in place. 

The door can be opened by 45 degrees so we didn’t remove them while mounting components. 

Just like we expected, the left side panel can house fans inside. 

Side panel fans are optional of course. Note that the fans you see on the picture below don’t come with the case. 

 The right side panel also features a similar filter, which can be removed for cleaning (rightside panel can not house fans).
