Dell owns Alienware from what i understand....(edit: I mean they literally own, as in control alienware, not as in they PWN alienware... just to clear up any confusion)
I notice there alienware laptops have features that dell inspiron laptops have...
The back panel and keyboard for example look identical.

Of course... you can not Overclock that processor because its from hp, i think you would have to flash bios right?(im not sure) and you would be wise to get rid of that Video card and throw in one 8800 gt 256 or 512, or 8800 gts 512 depending on your budget.
