Over in the IT lab, they have one of the new Intel-based XServes on display. I managed to snap a few photos, including one of the back of the server. It seems like there is now a graphics controller integrated with the motherboard, as evidenced by the mini-DVI port on the back:
Even though this machine had a PCI-E graphics card installed, you don't need to do this if you just want something simple for administering the machine.
