Design PCB Arduino

I need a design for PCB printing for an Arduino (any model that works). The idea is that the Arduino will take 3x Input signals through the MicroFit connectors and sends it to the fans.
The design should be ready for sending it to the printing company.

Requirements:
- PCB type header that you put on top of it.

- 3X PWM 4 PIN connector on it with 5Volts. https://www.aquatuning.nl/media/image/0c/9c/27/82352_1_600x600.jpg

- 8X 3 PIN 5V FAN would be nice, but I am not sure what the max amount is.

- 5X 4 PIN connector with 12V if possible.

- 3X MicroFit 3.0 Female INPUT

BOTTOM-MIDDLE: PWM SIGNAL INPUT

Original connector going to the HPE motherboard:

- Take power from all the MicroFit 12V connector, so possibly convert to 5V.
