Hi all. So I'm back again for some help
. On my first build ever I dropped a thread here and got Amazing help. I actually got about 90% of the parts recommended. This was about 3 years ago or so now. Looking to get a new build going with a custom water cooling loop this time and decided what better place than here for help 
So..... My main concerns are not the parts I need on hardware aspect, but the water cool parts like blocks and fittings. Also the tubing if to get acrylic or PEGT or maybe this glass I been hearing about. Also, what kind of water do I use? I read about like dye or something that is no good. And that this other thing like pastels also bad? I don't know maybe I have no clue what I am saying and mixing everything up.
Either way, if someone can help me out that would be amazing. I'm looking for a good water pump and reservoir combo; What size fittings I need; Again what blocks I need and tubes and whatever else someone can help me with.
Thanks so much.
Parts so far:
Case: Fractal Design Define S w/Window ATX Mid Tower Case
Processor: Intel Boxed Core I7-6700K 4.00 GHz 8M Processor Cache 4 LGA 1151
Motherboard: Asus Desktop Motherboard - Intel Z170 Chipset - Socket H4 LGA-1151 Z170-DELUXE (if I can afford it)
GPU: GTC 980 Ti or the 1080 when released
Ram: Corsair Dominator Platinum 16GB (4x4GB) DDR4 DRAM 3200MHz (PC4 25600) C16 Memory Kit
PSU: not sure, what do you recommend?
All help is appreciated.
