It's not over priced. Even though it's honkingly expensive it's not over priced. Find me another one, you can't. Without that datum the whole logic is flawed. Yes you can build a similar PC or Hackintosh but at the end of the day this is one of one.
As for snobbery? rubbish. We all like nice things. We all also want the best we can have. That's not snobbery it's just nice to have. Originally specced as it was per the service tag my Alienware Area 51 ALX (2009 model) would have cost ten grand. I know I've done at least a couple of grand on it myself, if not more. Not because I am greedy or a snob but simply because I like having nice things.
Most see that as working toward something and it being an achievement.
