You are on the right track, to the main part. It's hard to escape the fact that it's very expensive, but a lot of that cost is peripherals, which don't really count (as they are so subjective, everyone spends what they want/can).
If you want to overclock, you'll need a Z87 motherboard. Be aware that some Z87 motherboards position the CPU socket towards the RAM slots, and this can have a potential interference problem in this case when using an AIO like the H100i and an optical drive (The optical drive extends over the motherboard and doesn't give you much headroom in which to turn the pipes, it's something to keep in mind, but in most cases you should be able to work around it)
If you don't want to overclock, then the K-series processor is a bit pointless, you might as well get a socket 1150 Xeon. Similarly, the H100i is a lot of money to spend on something which will have near to zero purpose.
Memory is very expensive If you stick with a B85 board, then 1600 is as fast as you can find, but you can pick up a similar, more appropriate, kit for around $130. Doesn't make much sense to spend much more than that.
If you go to a Z87 board, then you have faster speeds on offer. While spending huge amounts of money on memory isn't usually the best return on investment, if you are willing to spend $175 then you have a huge selection on offer.
I'd suggest looking at a quality
1866Mhz kit like this, as a good place to start.
HDD is expensive. Caviar Blacks are great if you need the warranty, but they are dramatically more expensive than a Barracuda of the same capacity. I think if I was trying to do what you are, I'd use all the SATA ports available to me and split the storage between a couple of drives. It does limit future expansion, but 3TB is quite a lot, even in video editing terms.
Video card is a potential issue As Eduello pointed out, it's longer than the specs. Usually, there is a margin of error in these, but
this image would suggest that it's pretty accurate and you might struggle to squeeze it in. Contradictory to that, there is
this image and
this image and the suggestion that you can actually fit up to 305mm, but it might be a tricky install. Personally, I don't see any reason why it won't fit, and it shouldn't have any effect on airflow though some of the cooler will extend beyond the side vent.
If you can save money, this is the place to spend more. A GTX770 is more than sufficient for 1080P gaming right now, but looking forwards, and in a build of this sort of expense, you might want to consider spending more.
PSU doesn't make a lot of sense. Somewhere around the 550W mark will be more than enough for this build. It's perhaps worth extending your search to include ~620W PSUs as well, as they can often be similarly priced.
As mentioned, Corsair CX are pretty cheap, so I'd look to get something nice with a quality OEM.
The Antec HCG-620M is consistently on offer, which should make it a really attractive prospect for you.
Alternatives include the Seasonic M12II-620, G-series 550W, Rosewill Capstone-M-550, XFX XTR-550W and if you really want a Corsair, the HX650.
