I've never owned an alienware but fancy one as I'd be looking at either the 17 or 18.

Question is, if it comes with Win10 and I want to put Win7 64bit on it, whats the best/easiest way?   I'm not very techy when it comes to this sort of thing.  Incase I need to put the original Windows on, would it be better to swap out the drives?

Cheers
