You would not only need a K-Server, but also the licenses required operate a K System (Movies, Music, KEAOS use and updates, Metadata).
All owners start with at least a basic system. There are 3 basic systems, any of which provide the minimum necessary equipment and licenses to get started using a K System:
Mini-System (Newest addition to K) (Mini-Server and one 1080p Player)
1U System (1U Server and one 1080p Player)
3U System (3U Server and one 1080p Player)
As mentioned by John, buying a Player alone will not work, just as buying a Server alone will not work, and buying a Player alone, and a separate Server alone will also not work unless the Server you are buying has it's own licenses attached. If it does not, you would also need to purchase the appropriate licenses from K. (This could happen if someone was selling a Server from their system to add a different Server. They would need to keep their license, so the "sold" Server would not have a license).
More info on systems can be found on K's website (
www.kaleidescape.com), including how to find a dealer in your area. There is also a lot of info on this Owner's Forum, and members are always happy to help with advice.
Although we dealers can sell anywhere, unrestricted, I highly recommend you contact a dealer in your area to provide more info, and pricing.
Thanks for posting your question!!
