Kyle Memoir 🍉🐧Along with Lubuntu, it's worth mentioning legacy Ubuntu images remain available and those already installed on LTS versions have potentially many years (up to 9 or more) still supported on whatever they version they installed.
Memory is also upgradeable on many old machines that with a small hardware investment can become great Linux hosts.
