You can give it a good vacuuming, using a pipe-style vacuum cleaner.  For safety, I would say that you shouldn’t touch the surface of the computer while it is plugged in.  You should also disconnect it from the electricity.

What's the best way to get all the dust out of the PC fans?

I don't think a vacuum is sufficient. You probably want to use an air filter.  You can buy air filters that screw into the front of your computer.

How often should I clean the air filters?
