I will buy from Alienware again, even though I am not much of a gamer. I like the style and the performance is good as well. I have no beefs with support either. Pretty much run-o-the-mill for the industry, IMO. Granted, for non-gamer systems like a Thinkpad, one can do a lot better with other brands when it comes to cost.
My next toy will probably be a non-gaming machine from IBM or HP, though.
