Gigabyte motherboard from the same period with the issue ...
 three caps on the board are bulging or split on top.  I bought three of
 the same model boards at the same time and only one of them have had
 that happen.
 The cap failure is due to a formulation error.  The formua was stolen
from a competeing cap mfr, and they got it just a little bit wrong.  There
was a big write up about this when it was first discovered. 
   I haven't heard about that. Do you have a link to the write up? I did
hear about a lot of faulty caps due to a supplier that sold bad batch of
electrolyte to a lot of the cap manufacturers.  What formula do you need
for caps?  AFIK it's just a matter of buying them for the applicable
voltage. Yes there are formulas for capacitanace to achive the necesssary
filtering but the wrong results there won't cause them to burst.
