Yeah!!! I finally got my new NAS server.
A NAS server is a Network Attached Storage, which can be used as a central fileserver. In this case I bought a Synology DS207+ because of all its extra features.
The Synology DS207+ is not only a kind of file server – it is also a FTP, Audio, Media server, Photo, MySQL and Web Server etc…. Al this is possible because it runs Linux, whereby the possibilities for third part patches occurs.
A complete description of the Synology DS 207+ can be found here.
