Yeah, my daughters have cats in their rooms and you should see the furr I have to clean out of their computers.
Also, yes, I can instantly tell if I'm working on a smoker's computer by the odor. Other than that, it's really not any worse than regular dust. Disconnect all the cords; take off the panels; take out doors and go to work with some canned air. Voiding their warranty is just a cheesy effort to cut costs.
Incidently, the WORST computer I ever worked on was in a trailer for one of the contractors at the Rio Rancho, NM INTEL plant when they were building FAB 11. As most of you know, New Mexico is a desert and Rio Rancho is out on an open mesa and has blowing sand aplenty. I opened up this computer and there was sand in the case. Not just a little sand, mind you, but when I dumped it out, I was able to fill a coffee cup! As Adam Savage from Mythbusters is fond of saying, "Well there's your problem!"
