My nephews' PC (Dell Optiplex 790) was broken, as it turned out, the SSD had failed! So I replaced it with an old HDD (because that’s what I had on hand) and installed Debian directly via QEMU on the drive, since the PC was already open and I didn’t feel like using USB boot.

System: Debian (stable) + XFCE (nicely set up)
Programs: Learning software for elementary school and lower secondary school plus a few games
Browser: Firefox hardened with policies.json, all settings and addon installation blocked, only the addons I installed (uBlock, Ecosia, etc.) are allowed
Control: Screen time managed via Timekpr-next
Security: Instagram, Facebook, etc. and especially TikTok blocked via hosts; adult sites filtered via OpenDNS FamilyShield
