Help picking parts for gaming pc

Background: I (stupidly) bought a 980 Ti SC without checking to make sure my motherboard would support it. It does not. The good news I'm half-way to a new gaming PC! The bad news is that I mostly hate having my PC laying around in parts.

Following some of the sticky template:
* Budget: $1000 (for the rest of the build)
* Where do you live: USA
* Is there a retailer you prefer?: NewEgg, but only because I don't know too many others.
* Do you need or already have peripherals?: Already have, also already have GPU and SSD.
* What will you be using your Glorious computer for?: Gaming, random virtualization junk (VMware, GNS3)
* Do you overclock or want to get into overclocking?: Not unless it's stupidly easy and absolutely painless.
* Do you plan on going for custom water-cooling now, or in the future?: Same answer as the overclock question...
* Operating System. Do you need a new one?: I have one.

More in-depth background:
I haven't built a PC in about 20 years and I'm overwhelmed by the choices and need some help.

Here's where I am currently:

Some notes on the build, my preferences, and questions I currently have:
1. First and foremost, I don't have any great reason for picking any of the parts I did outside of what I kind of think I want. I'm looking for gear that I can set up and forget for the most part. If it has tinker-able options, that's cool and will pique my interest, but that is low on the priority list. The two main factors are stability and ease of use. Costs can go up if there's a decent reason for it.
2. I very strongly prefer vendors that have proven track records of producing quality parts. Specifically with the motherboard, I want a vendor that is very active in support of new gear.
3. I like a full-size ATX case so that I have room to work when I do have to open it up.
4. I would like parts that give me an easy upgrade path for the next time I upgrade, but I (probably naively) believe that the current parts list will be good for anything that comes out in the next 5-10 years.

Thanks for reading this far, I appreciate any help you all can provide.

Wait whaaa??? Explain... Explain... EXPLAIN...
(Dr.Who reference)
PS: how is it possible motherboard not to support videocard? Is it that old, that it doesn't have Pci-e slot? What's going on here?

Dumb move on the 980Ti. but your build is good enough. A slightly better CPU cooler might be nice, but the Hyper212 will do fine... probably?

I put a 560Ti and a bigger PSU in a store-bought computer a few (?) years ago. I know a guy on a very tight budget who is trying to build himself a budget gaming PC so I figured I'd give him my 560 Ti and upgrade mine to a 980.

Tried to get PC to boot with the 980 yesterday with no luck. Upgraded BIOS, did legacy and UEFI boot, uninstalled all drivers, loads of google-fu for a guy who hasn't done any major hardware work in 20-ish years, etc. 6 hours later and parts strewn all over, I think I'm down to just buying a new PC and giving my current build to this guy to tide him over for a while.

The cost doesn't really bother me and will be a nice thing to do, but the actual build part of this PC is driving me a little bonkers since I have next to no hardware knowledge anymore.

EDIT: Has PCIe. PC shows post messages but just hangs. When I switch to legacy boot it sits at post messages, beeps three times with a minute in between, then just shows me a single flashing cursor.

Are you sure you won't be just fine with newer power supply and not need to spend all that money for entirely new system?
What was the old system?
BTW, the new system is just fine. The Psu is overkill, but whatever... I am more curious about the incompatibility of motherboard and GPU...

Current PSU is a Corsair AX650 which I assumed was enough to power it (min 600W), but honestly I have no idea.

The computer itself is a HP h8-1214 with the HD swapped out for a 1TB SSD, the power supply replaced with the above, and a EVGA 560 Ti.

HP specs here:

When I emailed EVGA about it they said they believed that the motherboard did not support the card, which somewhat matches the info I was finding online regarding newer-ish cards. If I can get the 980 to work in this PC it would save me a lot of hassle, but I feel like I've tried everything I could find online.

psu is good enough for 2 980 ti's

why the non k part cpu and a maximius hero mobo? the z170 pro should work fine for your needs.

asus uefi has a very simple auto overclock so you might be better off going with a 6600k i5

if you want to get a better cpu cooler the noctuas are very quiet and and work great, althou some of them are quiet large, but with that case it wont be a problem.

also got case fans? yours comes with 2x 120mm but has room for a lot more, and keeping that rather expensive ssd cool will up it's lifetime, as well as the rest of your parts.

Does this look better?

For the K vs. non K part CPU, had no idea what the difference was so I just picked one. Thanks for noticing that.

CPU cooler & fan advice would be greatly appreciated. I've never seen a CPU cooler as big as those Noctuas, which is one of the reasons I went with the more traditional one that I did. Any recommendations on the Noctua cooler?

"Cooling System
Front 2x140mm/ 120mm or 1x200mm
Rear 1x140mm / 120mm (1x120mm included)
Bottom 2x120mm
Top 2x140mm or 3x120mm (1x120mm included)
Interior 1x120mm/140mm"

this is form your case's manufactures website. i would run the 2 that come in your case in the back + top and get a 200m for the front and 120mm for the bottom.
4 fans total with 3x 120 and 1x200. go with the back and top as outake and the front and bottom as intake. the air blown in would go through your gpu, cpu, and drive cage. might change if the outake for your psu is right next to the intake for your bottom fan since you dont want to recycle the hot air.
you can always just put a fan on every slot, but then you need to get a fan controller and at a certain point you reach the point of diminishing returns and have to say enough is enough.
also covering the fan areas you dont use would very slightly increase efficiency.

as for cooler, they are all pretty good, but the quiet power comes with a cost.
i would go
on the expensive side and
on the cheaper side

Motherboard is way overkill for 1151

You probably have too much RAM

and the PSU is a bit much

Maybe start here

A Hyper 212 is more than enough for most people

As for extra fans, can't go wrong with a 120mm fan 4 pack

May i disagree slightly?

2x4 please

Deepcool fan here, but there are much better cases than this one... The OP NZXT is just fine... I don't really see a reason to downgrade it.
And SSD... Comon guyz, SSD... It's some 40-42$... A-DATA SP550 120GB...

For the RAM I just hit the wrong checkbox, though it doesn't matter much for gaming if your RAM is single channel or dual channel

Otherwise it's a "Start Here build" his budget is much higher so he can throw in whatever extra

This looks much better than the original suggestion. I see no flaws in it. You could probably actually save a little bit of money as coming from DDR4-2133 to DDR4-3200 isn't going to help a whole lot. Seeing as you're not using the IGPU.
