My laptop is pretty jammed with cat hair. Best safe way to clean it out?

I’ve got about a year’s worth of Maine Coon hair shoved up in there, and the last time I had to have a Dell tech come out and work on it, the fool didn’t have anything to clean it out with. I absolutely, in no way, have the money to replace it if I destroy it. So what’s a relatively dummy-proof way to get the cat hair out? I think it would probably be too big of a job for those little keyboard vacuums, and they usually stink anyway.
