You will get more responses if you describe the parts with a link in your post.
Here are my thoughts:
1) To answer your question, please don't bother with liquid cooling, particularly as a first time builder. Liquid coolers are expensive, loud, less reliable, and they do not cool any better than a good air cooler in a decent case. I am not familiar with your case, but the specs looks good. You should have no problem with using an air cooler.
The hyper212 you selected is OK, If you want the best, for quiet, or cooling, then
I would suggest a noctua NH-d14 cooler or a phanteks.

2) For a $1000 graphics card, I would buy a newer tech 28nm GTX690. It is stronger and will run quieter than the 6990.
Also, the 6990 is a long card, 12.3" you case has a maximum graphics card length of 11.8"

EVGA makes a good GTX690, it is 11" long.

3) Nothing wrong with a 3570K. But few games use more than 2-3 cores, so a 3570K @$100 less would perform just as well.
4) A build with your budget demands a SSD. Buy at least a 120gb ssd. That will hold the os and a handful of games. If you buy a 180gb or 240gb ssd, you may not need a hard drive at all.
Samsung and Intel are the most reliable SSD choices today.
5) The sabretooth motherboard is ok, but overpriced, mostly for the design. Most any Z77 based motherboard around $150 will do the job just as well.
6) The ddr3-1333 ram is fine, but 1600 ram costs no more.
Ram is sold in kits for a reason.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will not support ram that is not bought in one kit.
Although, I think the problem has lessened with the newer Intel chipsets. Still,
it is safer to get what you need in one kit of 2 x 4gb.
And... buy low profile ram. It will avoid any coolerance issues and costs no more. The G.skil ares series is an example.
7) thermaltake rx is a tier 3 unit on this list

I would buy a tier 1/2 unit. you only need 650w, but 750w will run quieter.
