Well, since one of your first builds was just shy of $1,600 I gauged my build around that.

Things to note
1.) I'd definitely consider going with the newer platform over Haswell. While latency timings aren't really there yet, and price hasn't 100% reflected what you get, games will now steadily begin to be better optimized for DDR4 memory.
2.) Then With jumping to that boat you gain the 6700K over the 4790K/1231/1241 which yields gains from 2-8% relative. Closer to 12% synthetic in some cases.
3.) I'd definitely suggest going with the H7 air cooler. Just comparing it to the 212 Evo for sake of argument. It's smaller, better cooling relatively, quieter, easier to install & and in my opinion has a better overall aesthetic. While being only a few dollars more at $35.
4.) Personally with the price of your standard SSD coming way, way down in the last 1-2 years, I'd suggest dropping the mechanical hard drive initially to allocate budget to a larger SSD. You could go with a very high quality 500GB samsung SSD now and inexpensively add a mass storage mechanical drive later for $40-70 depending on size.
5.) While the 980 isn't generally the price to performance king in any genre, it does have one thing it's typical winning competitors(390/390X) doesn't have. CUDA. If you're going to be editing or making use of any sort of rendering resources, you'll benefit here. And in gaming of course the 980 is no slouch with a relative 9-16% performance lead over the 970, varying per resolution.
6.) Case I just opted for something cheaper to fit the budget frame, but without losing any CM features. And staying within the same sort of aesthetic.
7.) I chose the power supply I did mainly to accommodate possible SLI plans in the future. It's a pretty decent buy at it's price.
