Optimum fan placement

Above is a diagram of my case and the fans i have in it, i have a gtx 760 MSI card which creates the most heat in my system, The system is on a desk (not carpet) and only the front two fans are meshed. Any ideas on how to/ get more mesh for other fans please help!

Intake at the front/bnottom, exhaust at the back/top. Heat rises so having a exhaust on the bottom wont do anything even if you are force the air through with a fan.

Any idea on how to filter the bottom intake?

Just a bit of mesh of some sort, you said it's on the desk which is a good thing.
