:> ECC doesn't protect against certain types of motherboard address line
:> errors (since although the ECC is correct, the selected address is wrong, so
:> thus the data is wrong). There's parity protection on parts of the CPU
:> address bus, but I don't believe there is any protection between the memory
:> controller and the DIMMs for this type of problem. A handful of metal
:> filings is also known to cause problems when it is dispersed properly. :-)

:Your suppose to remove the motherboard before drilling holes in your
:chassis!!! :-). And be careful when you strip them there screws out,
:that little bit of metal filings is enough to through one for some

Forget the drilling! Blood conducts electricity... simply *installing*
a motherboard in those fraggin sharp-edged sheet metal chassis is enough!
