That's kind of like my T430: https://danangell.com/blog/posts/my-t430/

I wish it could go up to 32GB though. And the i7 in there shows its age. But it's still usable with modern software!

I had a T420s which is a bit smaller than the T430 and I really loved this thing. Did my whole scholarship with it, even bought a second hand to have as a fail-safe. Really nice machine for its time
