Dhl93449 - the article you linked to is one of many possible solutions. There are lots of people who have built very good computer based systems without building a system like Chris' system. Using a quality player along with an async USB connection can provide excellent results using a standard desktop or laptop. If you want to try a simple system, you can get a HRT Streamer II for $150, add a player (Foobar, J River, iTunes on MAC) and you are good to go. Like everything, it can take some time to build up to your "final" system, but you need to start somewhere. Chris' article is a perfectionist view. Don't let it scare you off.
