2tb is already a lot, 1tb should suffice but I just put 2tb just in case you needed lots of room since you had 4tb.
 


you need way more details than that

-location of where you are buying
-if you have a microcenter nearby
-if you are overclocking
-if you are going to run 2 video cards in the future
-parts that you can reuse or already have
