I know it isn't per the configuration specs, but I always have any
ethernet adapter right after the processor/memory, then the default
system disk adapter (typically an RQDX3 on my machines).

I figure I want the ethernet adapter as close, electrically, as
possible to the processor/memory to maximize throughput (those
nanoseconds do add up ... :-) and the same for the system disk
interface.

I've never done any tests to see if there is actually a
noticable difference.  Maybe one of these days...
