I took a bunch of stuff from work that was gonna get recycled including a decent laptop and a flash drive. I work in network admin and IT if that narrows it down. Never used Linux before though.
Edit: Thanks everyone! I'm down for some problem solving so I think I'm gonna go the Arch/Manjaro direction so I can learn my way around Linux generally.
If you want a daily driver, Debian. Maybe a variant distro that comes prepackaged and themed nicely out of the box. But stick with one that uses Debian's upstream repos and isn't like maintaining its own kernel release schedule.
If you want to fuck around and learn about linux then Arch. Or again you can use variant distro for an nice installer. But stick with the core repos as above. That means no Manjaro.
