Hello all, I have been considering buying an Alienware Aurora r6 for some time now (1600$). I aim to hit 4k while maintaining 60+fps. I mainly play solo RPG's when I'm not working or schooling, and it helps to get into the game more, personally, when I run all the settings on 'ultra'. my only concern is can the aurora run this without overheating? since it doesn't come with liquid cooling installed (as far as I'm aware). 
My other alternative is ordering all the components separately and buying a compatible tower and do the installation myself. my limit to spend is 1700$.

any advice? or anyone have an aurora r6 that can run these specs? or would building my own be cheaper and run better?
