Trying to Decide on the Best Build

Hey Tom's Hardware Folks,

I've been looking at building a new PC for use as a Steam focused gaming rig that will be almost exlusively hooked up to my 4K TV. I want to keep the form factor small and sleek since it will be in my living room so aesthetics are important. I've put together these parts so far but I'm concerned with some of the dimensions and making sure everything fits alright into the case. I really like the form factor of the AZZA CSAZ-103 (http://www.newegg.com/Product/Product.aspx?Item=N82E16811517029) and the SilverStone RAVEN Series RVZ01B (http://www.newegg.com/Product/Product.aspx?Item=N82E16811163252) so I'm heavily leaning to a build focused around either of those cases. I don't necesarily have plans to overclock, but I would like to have the option to if I want to at some point down the road, even if it's just a slight overclock. I wanted to get people's thoughts and ideas though about which pieces might be a better fit or if I'm completely missing something in this build.

Either:

-SilverStone RAVEN Series RVZ01B (http://www.newegg.com/Product/Product.aspx?Item=N82E16811163252)

Or:

-AZZA CSAZ-103 (http://www.newegg.com/Product/Product.aspx?Item=N82E16811517029)

And:
-SILVERSTONE SFX Series SX600-G (http://www.newegg.com/Product/Product.aspx?Item=N82E16817256109)
-Intel Core i7-4790K Devil's Canyon Quad-Core 4.0 GHz LGA 1150 (http://www.newegg.com/Product/Product.aspx?Item=N82E16819117369)
-EVGA GeForce GTX 980 Ti 06G-P4-4995-KR 6GB SC+ (http://www.newegg.com/Product/Product.aspx?Item=N82E16814487142)
-G.SKILL TridentX Series 16GB (2 x 8GB) 240-Pin DDR3 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231589)
-SAMSUNG 850 EVO 2.5" 1TB (http://www.newegg.com/Product/Product.aspx?Item=9SIA12K2GN1593)
-WD Black 4TB Performance Desktop Hard Disk Drive - 7200 RPM (http://www.newegg.com/Product/Product.aspx?Item=N82E16822236622)
-Panasonic UJ240 6x Blu-ray Drive BD-RE/8x DVD±RW (http://www.newegg.com/Product/Product.aspx?Item=9SIA8BU3CN9825)
-Dynatron K5 92mm 2 Ball CPU Cooler (http://www.newegg.com/Product/Product.aspx?Item=9SIA4M53ZV6371)

Are there any big gaping holes in my build that I'm missing? Is a 600W power supply going to be sufficient for all this? Is all of this going to fit into either of the two cases? Are there other things I'm missing?

Thanks for everyone's help on this.

Brian
