I vacuum all the time, but I use a small paint brush to bring the dirt and dust to the mouth of a dustbuster. Static can build during the running of a vacuum cleaner, so I think a dust buster is better.
I will start by getting as much of the dirt into an area at the bottom of the case to allow the dustbuster to pick it up.
If you are paranoid about all this you can buy a vacuum that has non static tools. 3M makes a very good one.
