A download machine/webcam server/remote connection - Via C3 800mhz
A real workstation - Athlon XP 3000+

Compslckr already said, you need a project not only a good case. Instead using Coolermaster or Antec you would have to look for quality components or a larger case.
I'm very happy with my Chenbro Genie. Solid, enough room for everything and quite good air flow.
Maybe you want to use a content manager instead develop your own site. There are some quite good content management portals for free. You can also modify it to fit on your needs. Try hotscripts.com.
PHP is a good tool, if you want do develop on your own.
