$580 Budget Build

Hi Guys,

I'm looking to build a $500-600 PC for my father. He mostly just watches movies (may HDMI out to a TV) and surfs the web, sometimes a bit of photoshop. I'm mainly doing this because he complains about how loud our old computer is, and because it's over 8 years old! He's sitting with an Athlon XP 1.6Ghz and 1GB RAM. This is supposed to be both quiet and powerful for the money (all Newegg):
