I also think that Alienware are a bit overpriced, but if I take a look at some other gaming laptops from other brands, they all are about the same price, or perhaps a bit less, but in my opinion the Alienware just looks really nice, compared to some other, really blocky ones.

I always wanted to configure one at mysn.de (the XMG P701 PRO Gaming), there I would get the same setup for 250-350€ less, but they use the Clevo laptop chassis, which is ok, but doesn't have an outstanding look.
