Liquid cooling/custom water loop/idk im a complete noob at this

where to even begin...
i want liquid cooling, but have absolutly flipin 0 idea how to do that.
ive only known about the liquid cooling that you buy that is basically just acouple of fans with a tube that connect to a cpu but apparently it is way WAY more complicated than that and has lots more to it and i need your help to figure out even the start. just saying, i only kinda read/went over the 2 main threads about custom water loops so i could probably read them more in depth and understand abit more but meh.
i have a gtx 1080 rog strix (the 3 fans thingy) gpu
an asus rog strix z370-h motherboard
16 gb ram crosair 2400mhz
i7 8700k cpu
Corsair 750W 80+ Gold TX750M psu


all of which are about to be transferred into a nzxt h440 (razer edition wink wink) case
(currently in the very old cooler master k380 case.)
and i thought maybe ill change my cpu cooling into liquid cooling as i currently have like... a giant block of Noctua NH-D14 which is big and does not look good and might not even fit in the h440 (i believe it will but meh)
so i thought maybe it would be a good idea to check for liquid cpu cooling and said lets buy smthing good but not too expensive so i went to the antec 240 mercury which was displayed in the best pc shop near my house and i thought that i might even get fancy on myself and get a 360 but i thought nah (i thought a lot of things apparently.)
but the 240 mercury is called ALL IN ONE so i got curious and found out that custom water loops exist (now i finally know what the heck all those random tubes mean in those 328528747982$ pcs...
just saying, this is 90% for the looks as i have about 0 intentions of even overclocking my pc...
i just want the knowledge (insert laburgini guy meme here) and the look of that crisp crisp neon green and black look
my cpu currently get to about 70-80c when in games like gta or farcry 5 on the highest settings and id rather it not going that hot especially if i some time in the future will look into overclocking.
so, where does one even start?
question 1. all in one or custom build with the help of you guys
question 2. what are the cost ranges for a mid level one (even if its for looks, i dont want a crappy one)
question 3. the basic parts of it? ill read the long article about this later, so thanks anyway if you dont answer this.
question 4. how does one put a blacklight inside a pc (1 trillion laughing emojis)
question 5. who do i give my pc to so he puts all the stuff in cause hellllll nah i aint messing with that... its mothertrucking liquid inside a pc full of mothertrucking expensive stuff
question 6. how does one even put a cooler on a gpu? are all in ones just for the cpu and customs for both?
question 7. should i continue with my Noctua NH-D14 for now and gather all the information and materials then put the custom loop (an all in one would be purely for the cooling cause they dont look as good as the loops) or buy an all in one and replace it when i can (i can buy an all in one for 150 dollars tops but id rather spend less if im going to replace it in the next year or 2)

and please tell me any more information that i should know
phew okay that took me like 30 minutes rip

Like mentioned above, a lot of research and understanding needs to go into such a project. It can get very technical, especially if you're not sure of all the basics and have at least a fair amount of building experience. There is also maintenance involved in custom loops. It will take a good quality AIO to match your current cooler. Custom is much more expensive, especially adding GPU, ect. For pricing, the sky is the limit with custom. Way to many choices to narrow down unless you know for sure what you want to achieve to ballpark the price.
Customers loop is expensive.

Try aio. The NZXT kraken is the best bling aio. Add to that dem rgb fans like the corsair LL and you are set.

Leave the gpu on its stock cooling if you don't want to tinker around with it.

Corsair has lighting node pro. It also got its led strips and icue software to control the rgb.
