"Perfect machine, I use it for virtualisation and performance is excellent. It's coming up on 2 years old and has yet to miss a beat. I have ran W2k8, W7, Vista and W2K3 I had a issue with W2K3 in that, the RAID set kept on corrupting, it was simply fixed by going back to an earlier version of storage drivers from Intel. Never had the issue with any of the other OS's listed above. I would recommend the Z800 as an alternative to having a noisy server sitting on your desktop."
"Absolutely PERFECT ROLLS ROYCE of workstations for CAD & rendering models. Read SW benchmarks - even lower duals can't take on this maths genuis. DEFINATELY going to drop in another W5590 dream processor to have the ultimate dream CAD machine with years of expandability to come. THANKS HP"
