Is it safe to use a humidifier in the same room as a PC?

I remember a long time ago I was reading some computer forum, and a guy posted that it's not safe to have a PC in the same room as a humidifier. He said that a humidifier will spread water vapor all over the room, and the water vapor has calcium and other minerals in it that will leave a thin white coating on everything. He said even the PC's motherboard will be coated, and that will damage the circuitry. Is that true?

You're just adding a little humidity to the air, not creating a sauna, correct?
The humidifier isn't blowing directly onto the PC?
You don't have water dripping down the walls, do you?

I've used one for years. No problems have ever come of it.

Edit: Mine's the "warm mist" type which boils water, so the minerals don't go into the air. No idea about "cool mist" types.

Fill it with filtered or distilled water thereby eliminating any mineral deposit issues.

As long as you're not increasing relative humidity to 100% and causing condensation of water vapor, there shouldn't be a problem.

Data centres actually recommend 45-55% RH. If it gets too low, static discharge increases greatly. As people said, just don't go crazy with it.

Depends where you live, but without my whole house humidifier I will dip into the high 30s in the winter, even down to the mid 30s if we get a good long stretch below -20C.
