Aware of the controversy surrounding the GTX 970 range and the 3.5GB rather than 4GB of accessible memory but power consumption and bang for buck they are still great cards that will last some time and dont break the bank price wise either.
Don't worry about the xGB figure on the end of most modern high-end graphics cards. It's typically only something you need to be concerned with
only if you're looking to hook up a triple-monitor (or more - yikes!) Nvidia Surround or Eyefinity screen-splosion.

I love Corsair cases! My modded 800d has served me well for the past... however many years.
Really liking the look of your build! The only thing I'd recommend including is a good Western Digital hard drive into the mix. A common practise if to house your operating system and standard programs on an SSD, and keep your miscellaneous stuff on the hard drive. I keep all of my work, music, photos, downloads, Steam games installed on a 1TB hard drive, for instance. It won't take very long to fill up that 120GB hard drive at all without the help of a secondary 'junk drive'. My Steam folder alone with only about 10 fairly modern games installed already weighs in at 136GB, to give you a better idea.
Note: Ah - somehow missed the hard drive list item... duh me! I'd recommend going for a 'Black' series drive as those things are smokin' fast and very affordable nowadays.
Returning to the case: That's a great case - I'd personally go with the non-windowed option as opposed to the windowed one as it includes an additional two optional fan mounting areas. Mind you, it's easy enough to mod your own fan mounts into the window. I used to have my case's interior lit up with LEDs and all sorts of junk but now I focus more on keeping stuff cool in there. My case is positioned in such a way that I can't see the window panel side anyway.
Optical drive: If you already have one sitting inside an old computer, just rip it out and use that one. It's so rare that I use mine now that I'll typically disconnect it once I've installed the OS and a few old-school games.
RAM: Unless you're intending to run a billion programs and render videos 24/7, you won't need any more RAM. I have 16GB in mine, and it's exceedingly rare for me to go above 30-40%, and I'll typically have 30 tabs open and some other junk running in the background.
SSD: Lovely choice! You can save a tenner and go for a cheaper Kingston model, but I'd stick with the one you've got. Shaz bought me that exact one to power my arcade and it goes from post to arcade screen (shelled) in about 8-10 seconds!
Monitor: IPS' have better viewing angles and better colour reproduction. But TNs are hella cheaper and are better for gaming. I've used both and while both technologies have gotten better over the years, TNs have always suited me better.
PSU: Unless you're going to SLi in future, you could get away with a cheaper model. 850 Gold is very solid future-proofing, though.
