http://www.pcbsd.org/ PC-BSD has as its goal to be an easy to install and use desktop OS, which is built on the FreeBSD operating system. To accomplish this, it currently has a graphical installation, which will enable even UNIX novices to easily install and getup and running. The system comes loaded with the "K" Desktop Environment (KDE), which lets users immediately sit down to a familiar interface. Also developed exclusively for PC-BSD is the PBI system, which lets users download and install their applications in a self-extracting & installing format, similar to InstallShield® on Windows®.
