Id instead get something like this
-your build doesnt have an SSD. you basically need an SSD at this point. the one i chose is extremely fast and is large enough to store all your games
-i chose the maximus ix hero as i personally prefer the extra usb ports in the back and better general IO
-high speed ram really doesnt do much in terms of gaming performance
-the hard drive i chose just so happens to be cheap and very reliable
-the case is a personal thing, up to you to decide
-i went with a 550w power supply instead. realistically you will never do SLI. its just not worth it unless you do it from the get go
-you dont need extra fans. the ones included are fine and you dont actually need all that much cooling
-the mouse is also a personal thing. i like the g502 more but thats me
