Computing Module
Computing Module feels worth carrying when you care more about long-term build progress than another quick sell.
Weapon Parts are worth carrying only when you already know which gun craft or upgrade is waiting for them; otherwise they lose cargo priority fast.
Weapon Parts are only good cargo when they unblock a real weapon craft, not when they sit in the hold hoping to become useful later. They are an uncommon weapon material, so the real choice is mostly about timing: keep them when a recipe or upgrade is next, and drop their priority when the run still needs fuel, healing, repairs, or matching ammo more urgently.
They matter most when they show up before the hold fills up, especially on runs where specialized boxes already fit what the crew needs.
