Should I change these things?

[Break_The_Net]

Ok, so I'm rebuilding my PC; And the only things I'm keeping are my 13600k processor, and my 2tb NVME. SSD. There are a few  things I'm concerned about like is my power supply enough? I believe it is but I will have a total of 4x 120mm NZXT RGB Core fans, and 5x 140mm NZXT RGB Core fans. So i want to have enough head room for that, The current power supply has a 750W configuration and an 850W, so I would like to know which one I should go with. And yes I will be replacing the 3x 120mm fans on the Thermalright AIO With NZXT 120mm's, and I would also like to know if that's even feasible, I don't know why it wouldn't be. And the 2x24gb kit I'm worried wont be compatible with the MoBo I have selected, and I would like to know if it is possible use those modules how much of a hassle would it be to set up in the bios, if any at all. Speaking of the MoBo, I selected a Z-790 due to convince, the aesthetics are great and it has every feature I would ever need. But due to it being a Z-790 it's quite pricey. So, to keep my aesthetics  and an ATX MoBo along with plenty of IO and room for one or two extra NVME slots what other MoBo's should I consider to save some money? So, yeah, my main goal here is to save some money on possibly overkill parts, and see if there are some compatibility issues with my RAM, and MoBo. Other than that any other critiques I am open to here as well, but please help because as great as co-pilot is it's not to this level yet, not that I would really trust it with these kind of questions either.
