How to go about controlling and powering 4 x 120mm PWM Fans

Yeah the heatsink fans in the servers are super loud. Honestly the reason for the cabinet. My tower is a self built silent machine. Unfortunately because of space issues in the other room the servers need to come into the live room.

I had thought about connecting something like this to the tower in the past.

I will look into this route instead. Thank you guys for the help. Maybe tomorrow I'll go pick up some lumber :-).
