Second last question on my build. I was following BITWIT build guide as he is also using a NZXT 500i case.

 

I've connected my PSU to my mother board. The 24 pin and the 8 pin.

There is still (picture below) 4 pin... am I suppose to connect another cable and connect this as well.

Trying to read the manual for mother board (MSI X570A but not seeing it ...)

most likley that is an additional 4 pin cpu header to give it more power.  Generally you do not need to plug it in unless your doing some serious overclocking.  If your not just leave it as is unless you really dont like seeing it empty

case fans generally are either 3 or 4 pin connectors.  The fan headers on your mobo which can be found in the manual are generally 4 pin.  Just plug the fans into them and your good to go unless u have a fan hub then u would plug them into that
