I had one for running very early builds of Win64 at Microsoft. It was a very aesthetically pleasing piece of hardware. The builds of Windows I ran on it were truly at the stage of "hey it built" so I remember getting a dialog one time that said something like "Invalid Error Code" with half the warning icon rendered and the other half random garbage. We moved on to IA64 and AMD64 shortly afterwards.
