My poor wife got shingles at 39 last year. Her doc was like “yeah it’s definitely shingles, welcome to firmly middle aged”

Ughhh that was my fear. Haven’t built a desktop in probably 20 years. I definitely worry about the time sink mostly in deciding every component, researching if it’ll work with linux, sourcing it, hoping it’s authentic, etc. Any recent guides you could recommend if I have to go down that route?
