/diy/ - Do It Yourself

I'm looking for recommendations on speakers for DIY use if anyone has any experience with them. I've never really worked with audio equipment myself though. I'm trying to find some cheap small speakers, like desktop computer size, that I can take out of the housing (or that have no housing) and mount internally in a DIY arcade cabinet I'm making. The only reason I'm asking is because I'm not sure if I can just pick up any cheap speaker set from Best Buy or Microcenter and get them out of their house easily or without damaging them, and even then if they'll be easy to mount. Anyone done anything similar?

While I'm on the topic, I'm not really very knowledgeable about electrical interference in audio, do I need to worry about that if I'm running the cables near a running CRT?
