So I've decided on liquid cooling my MSI 980 Tis. As this is going to be my first time water cooling I would like some critiques on my parts or advice so I don't end up buying parts and dealing with malfunctions or other reasons. I've done a vast amount of research but so far research doesn't always hold until I actually do it myself and gain the experience. I'll be doing this in my Nzxt Noctis 450 case and the main components are as followed:

Rad: Alphacool NexXxoS ST30 360mm (decided on normal width vs extra width as I'm going to have to mount my pump/res combo pretty much in front of the radiator between the end of my GPUs, as space/mounting orientation is a concern) https://www.amazon.com/gp/product/B007R79E60/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=A3GO5VFCNOM5I7

Pump/Res: EKWB EK-XRES 140 D5 PWM https://www.amazon.com/gp/product/B00P8VIBM0/ref=ox_sc_act_title_4?ie=UTF8&psc=1&smid=A3AFCSA6JU2B0W

Waterblock: EK-FC980 GTX Ti TF5 - Nickel

Fluid: Distilled Water (Or go with something that contains anti-corrosives?)

Tubing: XSPC FLX Tubing 3/8" ID

Misc: Y Splitter Adapter x2: Alphacool G1/4 High Flow Rotary Y Connector (GPU Waterblocks aren't compatible with GPU block bridges; upon exiting the pump/res it needs to split into 2 hoses for each GPU intlet and again to meet up upon exit of the GPUs)

My main concerns are the Y splitters. If they would alter performance or pressure of sorts making the pump degrade over time and mounting the pump/res somewhere. As well as any type of small issue that would be foreseeable that wouldn't be obvious to a first timer. Any feedback would be appreciated

Hello! Welcome to the watercooling club, LOL! I myself completed my first watercooling setup about 5 months ago. :)

Where are you planning on mounting the radiator? I believe you can mount it either in the front of your case or on top. Also, you can mount the reservior/pump just about anywhere, even if you have to drill a couple of holes.

About corrosion, I would recommend trying to keep all the metals in your loop as similar as possible (preferably copper). I use distilled water with Benzotriazole as a corosion inhibitor, (along with Copper Sulfate to kill organisms). Here's a couple great links that helped me immensely:
The Watercooling Guide, From A to Z - This is a long read, but it is very helpful.

PC Water Coolant Chemistry - Part I - These are also long,
PC Water Coolant Chemistry - Part II - but they are worth it.

I would highly advise against the Y-fittings. The only reason I would ever use a Y-fitting would be for a drain outlet.

I don't know if you are from the USA or not, but if you are, have you ever heard of Performance PC's? I have ordered several parts through them, and they have great service and good prices. Plus they have a great selection (versus Amazon).

If you have any other questions, I would be glad to answer them (or at least try to ;)).

By the way, the link I posted for the Benzotriazole was for a 100 gram container. Obviously, you wouldn't be using all 100 grams in your loop, only a few grams. It also comes in a 10 gram size, but it's a much better deal to get 100 grams. It'll last you a long time!
