Help deciding fans for H5 flow

Hey guys I was looking around as I intend to buy a h5 flow case and move all my existing components into it. Just wanted to ask however as I saw this gorgeous design that uses some different fans

For context, I'll be using my old AIO which is a Corsair one.

Is it possible to switch the fans of the AIO to a different one, also

Which fans would I need to get to have them look like the guys from the link and how many would I need to Max out the PC.

Thanks in advance, I'm not much of a PC builder so I'm not sure how I should go around doing all this .
