LinuxMCE

[screwballl]

you don't need no stinkin Microcrap to have a Media Center PC.

The latest stable version is 1.0 based on Ubuntu but there is also the latest beta version which takes advantage of KDE using Kubuntu and some extras that 1.0 doesn't have plus a much better installer.
I will be testing this myself in the near future.

1.1 Beta: Version 1 1 - LinuxMCE Wiki (Caution, the site may be slow due to the massive digg this site is getting)

1.0 Stable: Main Page - LinuxMCE Wiki

Very interesting, might make for a good user guide candidate (hint, hint)!
