Upgrading my Alienware x51 r2 and need some help/tips, I recently purchased 250 gb of samsung ssd and 16gb of Fury HyperX ram, from my previous 6gb. I have the the core i3 model of the R2. In the future I am planning to move the components to a new case. Then upgrade it with these specs, http://pcpartpicker.com/p/FXRmcf. also instead of the case in the link above, I was thinking about the rvz01 case. I also have a GTX 745 which is not good at all, my opinion. please tell me if this is a good idea and what I should change. Thanks!
