Looking for guidance--new gaming PC

I'm hoping to buy a new pc relatively soon, since the last one I built was from 2003 and I feel that I desperately need to upgrade in order to play the newer games that are coming out (BF3, ME3, Skyrim, etc).

I mostly play FPS games, but play some MMOs, RPGs, and strategy games as well.

I expect my gaming resolution to be 1920x1080 and will only be using 1 monitor for the moment, possibly upgrading to a 2nd monitor in a few months time.

Right now I'm looking for some opinions on this particular build, since I've been lurking these forums off and on for a while and I've saved up some money to put together a new rig.


Budget:
Under $3k (mouse&keyboard, monitor, speakers, etc. will be bought separately)

Expectations:
I want to have this build last me for the next 5 years or so, with minor upgrades to the gfx cards perhaps.

Usage:
80% gaming; 20% web surfing, movies, music, etc.

Special Needs:
None that I can think of.

Well, I do like the build I posted but I'm also thinking about the ODE level 3. The specs are comparable and I would save almost $500. That would help me stay on budget after buying a new monitor, speakers, mouse&keyboard, etc.

I definitely like the bigger case and upgradability... think I'll be pulling the trigger on this build! :)
