I built my mom a cheap PC like 7 years ago right before work from home took off, and at the time it was running Windows 10, but as time went on, it became apparent that the 8GB i built it with somehow wasnt enough so I upgraded it to 16GB. Fast-forward to now, where she's now running Linux because her work didn't want to support Windows 10 WFH anymore (but somehow also supported Linux clients??), and she doesn't even use 8GB of RAM, even with integrated graphics.
