I built a system very similar to yours a few months ago. Used the first 5 items on your list, as well as the Coolermaster CPU cooler. 32GB of GSkill DDR4 Ram, EVGA Nvidia 650 graphics card. I also added a 500GB Samsung 850 EVO SSD drive for my image-storing working drive. Reused some of my existing HDD and optical drives for longer term storage etc., rather than buying new ones such as those on your list. The cost for the new parts was about $1600 U.S., and I put them together myself. I'm very happy with this system. A quite noticeable improvement in speed; LR and PS move along lickety-split now.
