Win11 officially requires a TPM, but there is a work around. Basically you use a utility called Rufus to create an installation from USB and you have the option to remove the TPM requirement. This will let you install Win 11 on older hardware without TPM. It really pretty easy to do this. Just google it for online instructions and even step by step videos.
And about 14yr old hardware. I built my last PC in 2014 with fast processor/memory/etc. Over the years, it was updated with new faster SSDs and Faster Video card. It does gaming in 1080p and even some 1440p just fine. And if you are not a gamer, then why would you need the latest PC to browse the internet or run Word/Excel? You don't. Old hardware can run just fine for a lot of users.
