Wow—-sounds like a great machine——-if you could you post the specs ie. ram (company/ type) Mobo etc—-I am sure others might be interested as well. Always wondered about those opterons with all those cores. Its so helpful to have specs of a working machine to copy when making a new rig or buying components.

* not a bleeding edge video card because the primary purpose of the machine is to run virtual servers - but I did need something beefier than an on-board video card

Athena Power CA-SWH01B90 Black Steel Pedestal Server Case
* this was the only case I could find to fit the over-sized motherboard - only caveat here is that it comes with a single fan, so I may need to add more in the future
* also, I am not sure about blaming the case or the video card, but the when the card is seated in the mobo, it is still too tall to be secured to the case with screws
BE AWARE: I am still investigating this and it is probably AMD’s chip design fault…but I noticed in PerfMon that occasionally the total CPU processing would drop to near zero. It quickly shot back up to over 80% but would eventually repeat this. I suspect that this is caused by the on-chip L1 cache becoming invalid and needing to be flushed. Certainly a major performance if you are doing genetic research into cancer or something…but probably not serious for Carrara - just annoying for an uber-geek.
Honestly; I would have preferred buying Intel but I wanted tons of cores and the price couldn’t be beat. I was feeling better about the purchased when I learned that 3DAGE has used Carrara exclusively on AMD chips.
But for long-term, “real” server-grade work, Intel is probably the way to go.
