Has anyone used MSI MS-1727-ID1

Here is the link: http://www.msiwhitebook.com/
I am looking at the 17" Intel PM55 Core i7 DDR3 1333 GeForce GTS 250M / Radeon HD5870

I will configure it with the Radeon HD5870

Haven't used one. How much does it sell for? What are you planning on adding?

Here is what I am adding:
I7 720QM
Radeon HD5870
IC Diamond 24 Carrot gold compound
500 GB Hard drive
8GB DDR3 1333MHZ
Intel Centrino Ultimate N wireless
Windows 7 Professional
3 Year warranty
I will have them build it for a hole 19 dollars so I don't screw it up  

Normal work stuff word, excell, Power point, all that crap.

Games: I perfer role playing use to do FPS but I have gotten old and slow. Role playing is dragonage origional and orgins, Future diablo III and starcraft July 27th.

My goal with this build is a laptop that I hope will be able to play games for 3-5 years that is why I want the DX11 video card. I will upgrade the processor down the road to an extreme I hope. Would realy like to know if anyone here has one or knows if someone that built one. I looked at the M17x but I can get this one for 500 dollars less and with 2 more years on the waranty.
