I don't know why people keep telling video editors to get the 970, or some other higher-end GPU. Unless you're doing a LOT of transitions and video effects, or something more hardware demanding than video editing (like serious 3-D rendering), you won't need anything beyond what the 750 Ti or 760 will give you. This whole 970 craze, of recommending it for everything, is getting out of hand. If you're not gaming, and you'll be doing 3-D rendering, then getting a workstation card is better... not a gaming GPU.
But for video editing only: unless you plan on doing a lot of post-production effects, you won't need a crazy GPU. In fact, if you're doing mostly raw footage, you need to primarily be concerned with CPU and memory. Get whatever GPU fits into your budget, or fits your editing style; whichever is the most cost efficient for you.
turkey3_scratch- Please stop recommending overpowered GPUs to video editors, unless they genuinely need it. I've seen you do this with a number of video editing builds, and you seem to think it's a good idea. Games and consumer video editing software do not utilise the GPU in the same manner. Not every video editor will benefit from a high-end GPU.
OP- I'll edit your build a little bit, but not too much. If you plan on rendering long video clips, consider 1866 Mhz memory; that is the proverbial sweet spot for editors. Also, while 32 GB is an ideal amount, 16 GB may be plenty for your uses. If you're okay with overspending on 32 GB of RAM, then that's fine; just know you might not need it in real-world settings. With your case choice, I'd recommend a Corsair 300R at minimum. The airflow design is definitely superior to the one you picked. If you are fine with spending more, practically all of Corsair's cases have superb airflow and internal design. I seriously wish I was paid for each time I praised their designs lol. Honestly, they have more impressed me with the current case line-up than anything else; although some cases don't include certain things you wish they did. If you ever need spare intake/fan filters, or one for a spot that didn't come with a filter, I have a link for you (though they ship from South Africa, so costs will climb relatively quick). I would also knock the HDD down to a 2TB drive, until the larger drives have been around for a while longer. They aren't the most reliable drives on the market, right now, so I'd steer away from them unless you're running a mirror-style RAID configuration.
The only other component I'd recommend changing is the power supply. The EVGA 600B is okay-ish, but not recommended if you can find a better PSU within the same price range. For single GPU use, I would stick in the
XFX Pro 550w 80+ Gold on the cheap end, or the
XFX XTR 550w 80+ Gold if you like modular. If you plan on getting a second GPU, a 650-750w would be better. The
XFX Pro 650W 80+ Bronze is a good starting point for a semi-modular unit with more power.
Practically any XFX, Seasonic, or Antec PSU will keep you safe from buying a PSU that is inferior quality for the money. With most small cases, semi-modular and modular PSUs are highly recommended for cable management, but it's up to you.
