I have Polk speakers mounted in the wall (rear) with in-wall wiring to plate near media area (front). I am considering using a media center pc (I know it may not be the best idea!) as sound system using the in-wall spkrs. What are the considerations for converting connections? Are there any converters for the PC sound output (power and signal) to a banana plug and attached speaker?

Thanks!
