I might suggest that the price you pay for a H100 could go towards a i7-4790K which is a superior chip, particularly for multi thread usage such as rendering.
The stock clock is 4.0 and 4.4 turbo without overclocking.
I might suggest a quiet tower type cooler. Look to Phanteks or Noctua for some of the best air coolers. One with a 140mm fan would be quiet and effective.
Use low profile ram. Heat spreaders are marketing and get in the way of coolers.
A ssd is great for the "C" drive, but it can fill up quickly. See if you can't manage 240gb. Samsung EVO is very good.
What will you be using for a psu? Look to Seasonic XFX or Antec for better quality.
The R9-290 needs about a 650w psu.
I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
I have a bit of a concern about the R9 series. They seem to take more power and run hotter and louder than their nvidia equivalents. On newegg, you card has a 19% unfavorable (0 or 1 egg)set of reviews

By comparison, the similarly performing EVGA GTX780 ACX superclock is the most reviewed GTX780 and has only 2% negative reviews.
Yes, it is a bit more expensive.
