I might suggest a 500gb Samsung 960 m.2 pcie ssd.
Probably $40 more.
It is some 6x faster in sequential access but while good, it is not a game breaker.
The device looks like a stick of gum so you will never see it.
A plus for aesthetics.
I am very much against a liquid cooler when you have a nice case like yours.
I would use a noctua NH-D15s which will be half the cost and cool equally well.

My canned rant on liquid cooling:
------------------------start of rant-------------------
You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
How much do you really need?
I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
Past that, A AIO radiator complicates creating a positive pressure filtered cooling setup which can keep your parts clean.
And... I have read too many tales of woe when a liquid cooler leaks.
Google for AIO leaks to see what can happen.
While unlikely, leaks do happen.
I would support an AIO cooler primarily in a space restricted case.
If one puts looks over function, that is a personal thing; not for me though.

Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.
As a first time builder, you might use this:
MY build process:
Before anything, while waiting for your parts to be delivered, download
and read, cover to cover your case and motherboard manual.
Buy a #2 magnetic tip phillips screwdriver.
1. I assemble the critical parts outside of the case.
That lets me test them for functuonality easily.
A wood table or cardboard is fine.
2. Plug in only the necessary parts at first. Ram, cpu, cooler, psu.
Do not force anything. Parts fit only one way.
Attach a monitor to the integrated motherboard adapter.
3. If your motherboard does not have a PWR button, momentarily touch the two pwr front panel pins
4. Repeatedly hit F2 or DEL, and that should get you into the bios display.
5. Boot from a cd or usb stick with memtest86 on it. memtest will exercise your ram and cpu functionality.
6. Install windows.
7. Install the motherboard cd drivers. Particularly the lan drivers so you can access the internet.
Do not select the easy install option, or you will get a bunch of utilities and trialware that you don't want. Drivers only.
7. Connect to the internet and install an antivirus program. Microsoft security essentials is free, easy, and unobtrusive.
8. Install your graphics card and driver.
You will need to remove the graphics card later to install your motherboard in the case.
Make a note of how the graphics card latches into the pcie slot.
9. Update windows to currency.
10. Only now do I take apart what I need to and install it in the case.
11. Now is the time to reinstall your graphics card.
