S-M-S

If you're in the market for a powerful and reliable server operating system, you might want to check out S-M-S, or Slackware Mini Server. This Linux-based OS is console-based but can be managed through webmin interface, making it both powerful and customizable. Despite its name, S-M-S has all the features and functionalities of a robust server, with included applications like apache2, sendmail, spamassassin, clamav, squid, iptables firewall, mysql, cups, and more.

One of the standout features of S-M-S is TorrentFlux, a powerful PHP-based bit torrent client that can be accessed and managed from anywhere. This makes the server not just a choice for administrators but also for individual users who want to download torrents easily, quickly, and securely.
