Define power hit please - what else was hit/died? Was the system on a 
surge protector? (I ask becuase I'm in the process of building a 
"proper" data center in my basement and I'm currently thinking about 
power issues (as the first logical step after network connectivitiy).

Luckily the U5 is a low-cost item, so replacing them with a cold spare 
is not a big deal, but I am suprised the PCI riser/PCI NIC were impacted 
from a power line hit (I would have assumed the MB would have sacrificed 
itself and spared the PCI cards, memory and HDs. I guess the reality is 
the riser is wired directly to the PS, and when the PS died, it took out 
the riser.

Were it me, I'd question the remaining life of the U5 chassis and 
consider swapping it out with another one. If you don't have another 
one, I can send you one for actual shipping cost. If interested, contact 
me off-list.
