More screws means more chassis stiffness. A desireable feature.

If I was streamlining the process I'd use an electric screwdriver and a 3d printed screw holder.

You dont need a 'professional' repairman to screw things in. Most people aren't intimidated by screws, that's silly.

SOCAMM2 is a great form factor for user upgradeable DRAM. The fragile pins are all on the relatively cheap interposer. Id like to see an equivalent standard for NAND. M.2 uses more z height than necessary. Especially for 2 sided support.
