I bought a DIY Edition Framework Laptop 13 with an i5 1240p for about $1050 after buying my RAM and SSD on their own. This is the best option if you’re into modularity and upgradability and second only to buying used when it comes to environmental friendliness (in my opinion). Battery life isn’t anything to write home about at least on 12th Intel though, supposedly 13th gen Intel CPUs do better

Otherwise, System76, Tuxedo Computers, and Laptop with Linux are probably good options if you want Linux pre-installed. All 3 of those take Clevo laptops and make them their own.

Starlabs also looks like an interesting option, but I believe the Starlite is the only option under $1000 USD. As far as I know, they’re the only company that makes their own laptop chases from scratch for Linux.

GNOME 44 with a couple extensions. I’m a big fan of its general look and feel
