So I'm sick and tired of listening to talk radio all the time in the morning when I get ready for work. I'd really love to be able to listen to shoutcast or pandora instead of 95% commercial/talk but I'm worried about the conditions of a bathroom if I put a PC in there with the steam and heat and what not.

Question 1: I have a walk in closet in the bathroom so I could put the PC in the far corner of it and just wire up some speakers through the wall to the rest of the bathroom, but do I need to be careful what type of speakers/wire I get?
Question 2: Does anything exist already to do this for me without building my own?
Question 3: Are there water proof battery remotes that can control the radio functions?
Question 4: Recommended parts for such a build? Is it possible to go headless and manage from another pc in the house to keep the build cost down?
