Having a hard time making things ouit with this side window/fan.
Have you cut a hole in the windor for the fan?
How is the fan attached to the inside of the side panel/window? as I think I can see the holes where the screws would go into the fan and I can't see screws in there. (might just be the light reflecting though.
Personally i think it slightly ruins the looks of a nice clean build, but if you need the airflow then it's a valid addition.
Edit: Just had another look back through the log, and as far as I can see the side panel doesn't have an appature in it for the fan to draw air in through.
