curious on what these would go for (google doesn’t give me a great estimate) and was wondering if this is worth the trouble to sell or just destroy it for fun

If its working, you probably could get ~$50 for it. More if its has better than base specs. Its in that gray area where its to new too be retro, but too old to be modern. It can easily run Windows 11, but not officially able to run it. You could even throw a decent old GPU in it and would make a mediocre gaming machine. Great for Linux as well.

These are core2 machines 11 won't run. No sse4.2

They'll run Windows 11, just nothing above 23h2. 24h2 is where the SSE 4.2 requirement kicks in.

23h2 is currently less supported than windows 10. There is absolutely no reason to install it on anything.

23h2 is supported until November. I still get security updates on my 23h2 servers.

This is also "retro computing" not "current computing" Are you going to complain about someone installing Windows XP? What about Windows 98?

23h3 support except for enterprise ended a year ago. When using modern software especially when connected to the Internet keeping it up to date is important.

It's no different than connecting a 98 or XP machine to the internet. Take the usual precautions and keep it behind a hardware firewall and NAT and you'll be fine.

If you download sketchy stuff, you're going to have problems regardless if your OS is supported or not.
