Extra part needed - some electronic stuff from Samsung NP350 (or 355 or other like) notebook:

• Motherboard with CPU, HDD (or SSD) and RAM (SODIMM).
• Soundbord with cable
• On/Off board with USB ports with cable
• 8 screws M2x10
  You can find these parts on Ali or e-bay.
  Also you will need to increase soundboard cable. Simplest way to do that is cable replacement between sound- and USB-boards (it needs some soldering).
