Build Your Own Computer -- Ultimate Budget Box

ArsTechnica has created a system guide for what they call the Ultimate Budget Box. A desktop computer created for normal SOHO activities -- document creation, a little web surfing, email, etc. They reckon they can put together a good, reliable machine for under US$500. I'm going to list their recommended components here to remind myself to have a look around next year and see if I can put the thing together for under US$350.
