Mini-itx budget build for non-gamer

APPROXIMATE PURCHASE DATE: Within 2-6 weeks.
BUDGET RANGE: $600-800 USD.
SYSTEM USAGE: Web surfing, watching videos, listening to music. NO GAMING!
PARTS NOT REQUIRED: Keyboard, Mouse, Monitors. Windows 7 Home, 500GB 2.5" SATA HD.
COUNTRY OF ORIGIN: USA
PARTS PREFERENCES: Intel i3-540 but open to suggestions (I used to prefer AMD CPUs).
OVERCLOCKING: Nah, don't care-prolly won't.
MONITOR: I've got two Acer X233H 1920X1080 monitors and they only have one VGA and one HDMI port on each.
PRIME CONSIDERATIONS: Small desktop footprint, As quiet as it can be considering power needs. Multi-monitor support using VGA and HDMI is essential.
SKILL LEVEL: Advanced. I built my own desktops since the 386 days but stopped 7-8 years ago and bought laptops exclusively since then. I am largely ignorant of the current state-of-the-art in home builds.

ADDITIONAL COMMENTS:

1. An Atom system would be too underpowered but an Intel i5 might be too much for my needs.
2. I tend to have multiple browser windows open and an excessive amount of tabs open in them.
3. I watch a lot of video podcasts or have a Slingbox window open.
4. I listen to music with my Zune client or Pandora but don't have fancy sound requirements. A couple of desktop speakers work just fine.
5. I don't care about HD or Blu-ray.
6. Did I mention small and quiet? Mini-itx is essential and as quiet as can be. CPU heat sink preferred but not a fetish. This is also why I'm tending towards on-board video: no GPU fan noise.
7. I might eventually upgrade it for use as a home server or HTPC but this is not an essential consideration.
