NetBSD is a free, secure, and highly portable Unix-like Open Source operating system available for many platforms, from large-scale server systems to powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research environments, and the source code is freely available under a business-friendly license.
Origin – Home Page: USA – NetBSD
Price: Open Source and free
Comments: NetBSD is a server-oriented distro, and offers a menu-driven installer. Like OpenBSD, it uses the traditional root user system, and also like OpenBSD, you will have to spend some more time after installation before you can have a usable desktop.
