Bummer they are nice machines. I have the original 1.6 single CPU machine and it works great, but slower then my other DC 2.0GHZ PCIE models. So many decent motherboards end up dead because of the switch from lead to silver solder and bad caps. Capacitors can be easily replaced but I don't have the skills of equipment to do reballing (could save a few video cards I have as well if I did).
