These step-by-step instructions will walk you through the process of installing an HDD or SSD for internal storage in Nucleus.

Step 1: Make sure you have everything

  • 2.5" HDD or SSD with a drive height of 7mm or 9mm
  • 4 black screws
  • 4 silver screws*
  • 2 hard drive rails*
Your hard drive rails and silver screws may already be installed inside Nucleus, if so, simply move on to step 2
