Hello, I am wanting to build a pc around $2,000. I want it to deliver high speeds in gaming, in ultra settings and also keep really cool and quiet. Please, I would appreciate it if you would make a new one, and maybe take out the water cooling and add a nice air cooling that delivers good cooling and being quiet. I am also on the edge with the mobo, and the PSU. Other than that I will use a m325 for the mouse and get a good keyboard. So please if you want to replace these parts upload the links in the comments.

Here is something I'm working on not much different at all but felt like sharing. http://pcpartpicker.com/p/LWxbCJ

For gaming, an i7 is waste of money. Games don't yet support HT and are still more GPU bound than CPU
If you want to go with the H100i, remember to replace the stock fans, they are REALLY loud.
R9 290 is just as powerful as a GTX 780, but has 1 GB more VRAM and costs 100$ less.
For gaming, 16 GB is a waste, 8 GB is more than enough
Even the 650W psu i went with is pretty much overkill for single GPU setup, but it is good to have a bit of headroom so you won't be maxing out your PSU ( i would assume this system to take anywhere form 400 to 500W when OC'd)
Hope I helped :)
Also, you do NOT need more than 8GB of RAM for gaming. And I agree, I have an R9 290 and it's kickass! It actually beats the 780 in most benchmarks when overclocked. It overclocks very well also.
This is what i have thrown together. I also agree that 16gb of ram is why to much.
