Also as a mention here, a good laptop can be of any age. If you want help looking at older laptops thats my game. I don’t know ANY of the newer hardware outside of macs and a few servers (and amiga’s). BUT, BIOS laptops are totally my game. I can help there if you’re willing to go back that far.
Other than that, find a y40-70 or something like that. GREAT wifi (AC) and you can install linux, OSX ( Why in the World: Hackintoshes (Y40-70) ), whatever. Plus you get a GPU that is around a 260X. They go for cheap on craigslist because people break the hinges. Easy fix with superglue.
