How can i install a case fan on the side panel of my case

[YourAverageGuy]

I have the cougar challenger mid tower case
and on the manufacturer's website it says you can install a 120mm or 140mm fan on the side panel (http://cougargaming.com/fileadmin/downloads/Challenger%20datasheet_0726-1.pdf)
so i opened my case and could not find any place for the screws so can anyone with the same case tell me how to do it? thanks

The side panel has a grid of holes, right?
4 of those will line up with the screw holes in the fan.
Screw goes through the case, and screwed into the fan holes.
