Will it be enough???

I am trying to build a computer and i have ran into questions.  My build is going to be in a Evolv X case with a MSi B550-A pro motherboard. I plan on getting a Ryzen 5800x CPU with a Nvidia 3080 founders edition. I am going to use my old ram from my current pc which is XPG Z1 ddr4 3000MHz(upgrading in future). I will be cooling my pc with a NZXT Kraken x73 RGB 360mm AIO with the radiator on the front panel with the tubes on the top. I will also be getting NZXT triple 120 mm AER RGV 2 starter kit for the top with the RGB controller and 1 AER RGB 2 120mm for the back of the case. I will be using a NZXT C750 power supply to power all of it. This is my build that I have done some weeks researching and putting together to put together my dream desktop. My first question is if I am going to have enough spots on my motherboard to pug everything in and not have any useless equipment. I am a bit confused with the aio if it comes with an amd bracket or not I have read mixed thing and I feel that it is weird that you need to plug the aio into usb header across the board. 

 

Thank you all in advanced for responding it means a lot.
