Building a Whitebox/Barebones Laptop

Hey I'm looking to sell my old laptop and probably get around $400. I want to make my own laptop but i have no idea of what to get. I saw similar threads on building a pc and i was looking for some help on laptops. I guess i am looking to spend no more than $1200. Can anyone help me out here? Thanks

I think you would be much better off buying a off the shelf laptop. Not to many regular people build their own laptops.

yeah alright. I have heard that before but wasnt really sure. You recommend any brand? I was thinking alienware or dell

Out of the 2 you ask about, Dell. Personally I would go with an IBM Thinkpad. But I don't know what you plans for the laptop may be.
