20 years ago it was a chore but nowadays it's faster than baking a cake. 10 minutes prep time (configure os and add drives), 10 minutes bake time (installation) (or 10+ hours bake time if count building the array)

But let's assume you don't have a clue and have to follow some tutorial and do some reading and it takes you 2 hours. That's amortised across a decade. Especially now when easy distro upgrades are basically unattended so you can use the same setup for a decade and stay up to date.
