Thanks, I was just curious more than anything. Would be cool to own a HPZ800/820/840, but I really have no use for one. I see that you own a Z600, how do you like it? If I did own one, I would probably throw Linux on there, as well.
BTW - here's a really cool in-depth look at the design and engineering that goes into these HP Z-Class workstations -

BTW, and the end of the video a guy from HP compares an cMP to a Z820; yes, there are situations where the 820 is faster, however there was an article I remember reading where even though the 820 has more cores, the advantage of OS X allows the Mac Pro to actually be faster to MUCH faster in a few other tests, though only in a select few.
