That's a misconception. We've a P3 PC which is outside on the veranda of the 1st floor. It is brought back inside only when there are cyclones. It is covered everynight with hard plastic stuff like the one used for covering cars. - 7 months now since it was out and till now NO BREAKDOWN - just minor inconveniences when it comes to bugs - but there are anti-bug stuff in the form of powder!
