Sorry to barge in like this but a couple of years ago I designed and built media system called the PC Integrated Amplifier. Nothing new really. I'm sure it has been done to various degrees in the past. I finally got around to putting up a web site explaining the concept and detailing the construction. It was a great project (not the web site!). I spent considerable time working on the layout and simplifying things as much as possible. I wanted to share the project and maybe generate some feedback. Nothing for sale, no Flash, no Java, no BS, lots of images and links.
