Wanted – WTD half decent gaming laptop

I have half decent one:
Alienware Alienware 15 – in excellent condition, screen was replaced 2 months ago(had few dead pixels) and it just got a brand new battery, both fitted under the Dell warranty that is until January 2018, I wouldn’t class it as mint as I am sure someone can find some signs of use. It comes boxed.
