Need computer parts for basic use (x2)?

I need parts for a build. I have built computers before but only for gaming. I'm not necessarily up to date with the latest parts and what is good because my computer can last a while. However, I would like to build 2 mini ones for my family before I leave for college. My mom and my brother do basic YouTube browsing, Facebook, etc with lower end gaming. My brother mostly plays Roblox or Minecraft, so I'm not necessarily looking at a graphics card. I need two PC same for both. No need for big hard drives, probably 500GB max. I prefer Micro ATX in this build with a small tower, (smaller than mid tower). My budget is around $400-500 a piece, if not cheaper. I prefer Intel. Do not just give me PC part picker and tell me to make it myself.
