This new offer reminds me of Zareason, who offers a broad range of hardware with any flavor of Ubuntu GNU/Linux preinstalled: desktops, laptops and servers. I did purchased a workstation from Zareason in Autumn 2008 and found it to run smoothly.
PC-BSD has already been mentionned on this blog. Capitalising on the KDE desctop environment, it is probably one of the most user-friendly UNIXes after Apple Inc. OSX. PD-BSD relies upon Free-BSD, but it also uses its own package management system (PBI) to install applications. There is already quite a broad choice and the list keeps getting longer.
It is nice to see it an OS as promising as PC-BSD running on fully supported hardware.
