Travel, School, and Silliness

Cut and Dry - This is what I am looking for in my next 2-4yr lasting computer.
Note: - I care not for Vista, or Win7, thats like 2-3 yrs down the line and ill get a new system for it.
Note: I dare not pay more than 1k for a desktop.. thats the budget.
Note: I will probably buy a $300-400 1920x1200 monitor down the line and a 200$ G19.

Ok that said: I want to run highest resolutions. Always: Dual-screen. Budget 1k.

Case:
- 140 (CoolerMaster NV690 nVIDIA Edition ATX Mid-Tower Case)
- vs 230 (CoolerMaster HAF 932 Full-Tower Case)

Power:
- 600W - 650W (120-200$)

HD:
- 10000rpm , low capacity (100-200$)

CD-drive:
- Possibly just grab from old machine.. no need to upgrade

Standard CPU Cooling Fan:
- not overclocking so (20-50$)

THE MEAT:
1. CPU: - 9950 Phenom 64X quadcore - $245
2. RAM: - 2x2GB 1066mhz ram - Patriot $85
3. Motherboard:
- MSI K9A2CF-F AMD790x (2pceislots) ($120)
- vs MSI K9W2 Platinum nforce 750a AM2+ (2slots) ($185)
4. Graphics Card:
- sapphire radeon HD 4850 1GBDDR3 (227$)
- vs 9800GTX+ cards ($200- 280) ... 1GBDDR3 prefered on high end.

Anyways... now i just gotta find a way to get 3yr + warrenty on all this for under 1k.
Any suggestions?
