The Case of the New Computer

Last night it finally happened, the Dell Inspirion that I had been using for the past six years (not to mention three house moves) gave up the fight. First off, this was a solid computer. Used for nearly every facet of my life during the past six years including:
  • Partitioned web server when I started my own consulting business in 2004.
  • File server for 100+ GB of pictures, music and video, including a huge growth in files with the births of two sons ('06 and '08).
  • Accounting system for the entire family.
  • Gaming system before I bought a Wii. My wife and I spent many an hour playing Civilization I, II and III on this piece of hardware.
  • Home office computer part deux when my wife started to work from home after our move to Austin.
  • Learning platform as I played around with education myself on the innards of computers, programming, HTML/CSS and networking.
Alas, all good things come to an end. The research towards a new computer begins today, but I'm looking for suggestions from all of you, who know me fairly well at this point. Tell me what computer would work best for my family, here are some critical points:
  1. I use a MacBook Pro for work and love it.
  2. My wife has a separate Dell for work now and she loves it.
  3. We need a central computer in the house to serve as a primary system to hold all of pictures, videos and music for networking throughout the house.
  4. The computer does not necessarily need any "Office" applications.
  5. I need the computer to be partially partitioned as a web server to host my blogs, including this one and several family blogs.
  6. I would like to start doing the family video editing on the home computer, whereas today I use FinalCut on my 15" MacBook Pro.
