now you can add more hdd space if you need it get a better mother board and a better gpu but other then that this should get the job done nicely
this setup is just like mine except
i have 16 gb ram and 128 gb ssd and 5.6 tb hdd space and a gtx 760 and i use this on my 3d 120 hertz projector on a 120 inch screen so....
i added a better GPU better SSD
put os and your Favorite games and apps on the ssd
as for the 4 tb black edition western digital would be excellent for the rest of your games/movies or what ever
as for the motherboard CPU and cooler they do not need to be changed there fine its what i have its perfect i have no complaints since i built it a wile ago do not know when it was built but it is less then a year tho maybe
just under.
one last this the cpu is pretty much a non oc no igpu 17-4770
you do not need built in gpu adds more heat better with a gpu which i put in the build
and this cpu does not need to be oc tho it does have turbo from up to 3.7 Ghz
its a quad core hyper threaded so its a virtual 8 core
the motherboard i only got cause i only wanted up to 2 gpu now if you want more then 2 get a different motherboard
water cooling if you want but temps with air cooler are amazing highest temp i get wile gaming with 6 games on ultra running all at once is 43-48C the highest
so water cooling if you want to up to you
any questions just ask
hope this helps xD
