Home Server Build Advice - Overkill?

[robc606]

Hey Guys,
I'm just getting round to building my home server next month. I've built up a list of parts but I wanted your guys opinion as I'm not sure wether I am going overkill with the parts for what I want the server to be doing.

Alright so the server requirements are;

• 
  Small teamspeak server (10 man).
  Plex media server for streaming all my content to everywhere, including a raspberry pi hooked up to the main TV running XBMC.
  Sonarr or Sickbeard/rage for tv show torrent management.
  Couch potato for movie management.
  File system serving content to devices internal and external (Say my laptop on the move)

If anyone has any recommendations for parts that will do the job and save me some money I'm all for it
Also should I be looking at getting some more storage for raid?
Has anyone got any experience with linux servers and setting up multiple drives as one big drive/space on the os?
Cheers

You don't identify the OS, but since I suspect Windows, I would recommend 8GB RAM which will also have the benefit of running dual channel.
