Several things (which you'll probably ignore): I wouldn't reccomend buying a computer from a relatively small company, especially one whose website I could not find.
If you can't find their website (which ironically, must be in over ten different threads on this board, probably more), your advice will most likely reflect your technical expertise.
As for your recommendation of Alienware over Sager, Sager has been around a lot longer then a more recent startup such as Alienware (not to mention Alienware only recently began reselling Clevo laptops in the past few years, since about the Clevo 8880). Alienware simply jumped on the boat about 3 years ago so to speak.
So if you can't find their website, and you think the smaller 9 year old company (Alienware) would have more experience and better support then the larger 20 year old company (Sager), yeah, we are going to ignore your advice.
