The 512gb SSD is huge, but if you've got the cash feel free.
A 1000W PSU is also a bit over the top. Again, if you've got the cash feel free because it won't really hurt anything, but if you want to save some cash, you could get a 750W (or even 600W) PSU and still be fine.
This Website is a good calculator to figure out how much power you actually need. Remember to get a quality PSU (Seasonic, Corsair, Antec, XFX, PC Power and Cooling, Silverstone are my favorites).
Any reason you chose AMD? These days, AMD CPUs are mainly used for lower end builds because they are cheaper. You have a lot of high end parts in your system so it seems like an odd choice. Of course, I'm not sure what programs you use so if you've looked and benchmarks and AMD beats Intel, ignore this paragraph.
I personally don't like those self contained water cooling kits. You can get an air cooler that works just as well for about the same price and you never have to worry about it leaking. That's just my preference though, a lot of people use them and love them.
