You are underestimating how good a cheap coffee grinder is. 10 seconds to do what a manual grinder takes minutes to do, costs the same despite being powered, and it can do half an Oz at a time, more if I feel like being careful. One day it’ll be too gummed up for the motor, and then I’ll go spend another 15 AUD for another one, unless it’s gone up in the years I expect it to last.
Depends on the game you play. M.2 vs Sata SSD isn’t a huge deal for game, but either of those vs HDD on a game with actual loading times is a brutal difference.
