The one you linked in the description above, will fuck you over in the end. Its not build to last, will probably overheat often because of the cooler. I know a guy on twitter that helped @Astro with his PC. PM me if you want his @, he's been internet jesus for a while.
I would suggest you build a desktop but seeing as you've already said you don't want to do that I ha e nothing else to add. Personally think a gaming laptop is a waste of money because you can't upgrade anything.

I'd highly recommend a small form factor desktop PC instead of a laptop.
