The selfish part of me is saying don't throw it away without uploading first.
A compromise would be to load it all into radarr and then search for upgrades. Anything that doesn't find an upgrade over period x (like maybe a month?) Consider uploading those somewhere.
Of course this is a lot of work and a lot of storage, it's up to you.
You could also mail it all to some release group people.
