Nothing is hard when you know what you're doing. :)
Being able to completely wipe your compute machine and not worry is nice and imo easier.
For only Jellyfin, then I agree - if that is where it stops you could run it all on an N100 integrated motherboard and have a lean sleek system that hosts your files and your streaming server. But when your services starts being too much for the N100 then it's nice to separate it a bit and for me it feels natural to split it between compute/storage.
