What do you like about orcaslicer? I’ve mostly just used Cura because it was the first one I picked up and it seemed to work fine.

Some stuff that immediately comes to mind

• FreeCAD might be too resource intensive
• OpenSCAD maybe a bit of a learning curve for more complex designs, but can be used for simple stuff
• Tinkercad online basic 3D design
• Cura slicer I’ve used (in windows) and it seems fine
• PrusaSlicer
• Slic3r

Googled “intel whitebook” and this is the first link https://www.intel.com/content/dam/support/us/en/documents/laptops/whitebook/Intel-Whitebook-Quick-Start-Guide.pdf

It suggests there are two M.2 slots under where you are holding your drive.
