Sun has produced a multi-media tours of the new T5120 and T5220 Servers and a similar tour of the Sun Blade T6320 server. Both of these "Interactive System Tours" can be found on the coolthreads page.
The T6320 tour is a single brief video. The tour of the T5120 and T5220 is more elaborate. There is an intro video and the ability to interactively rotate images of the servers. You can select different views, (rear, front or internal), then click on key components and more information will be provided about that component.
