any chance I can add any fans or other things to this pc?

Solution
Protect your intakes with a dust screen whatever you do.

My current computer has 4 intake fans and dust screens on each, making a positive pressure situation. For over a year now its been like that, and I clean the front and top intake screens but have almost no dust inside the computer. I know it doesn't make sense from a "heat rises" flow, but with all those fans pumping air in stays cool.
