This board is built for a custom water cooling loop. This will require fitting's, tubing, radiator, pump, reservoir and gpu block if you want to add the gpu into the mix. There is quite a bit of planning involved in building a custom loop IE: getting components that will fit properly in your case and then plumbing the whole thing. If you truly are interested in a custom loop I suggest looking up Jayztwocents on youtube. Also one thing I missed during this process is your gpu should be reference or have a specific block made for the exact custom pcb.
I have a custom loop on my maximus IX hero.
Here is a random google image search of something like what you'll end up with

Custom water gives you a quieter pc, looks better, and has more overclocking potential. In my case I could have got a better gpu for the money I spent, or better ram. But I wanted to build a machine for tweaking and looking cool AF in the process so my budget had a custom loop in it.
