I'm surprised to hear this - are you talking about 2g or 10g?
the list price of myri 2g is about $450/port (nic+switch+cable)
I'm also interested to hear your statistics on reliability.
my organization has ~10 myri 2g clusters (600-650 nodes),
installed over the past 4 years, and have had few problems.
we don't have any myri 10G hardware - have you had problems with
their 10G nics or switches?

it's all about your research focus. if you're pushing the edge of
computational technique, you look to full-custom software. if your
computation is mainly just an adjunct to lab work, you look for an
shrink-wrapped application (which, like it or not, are more commonly
commercial - consider gaussian vs nwchem/etal)
>> I am thinking of building a Beowulf of 17 dual-core nodes, one head node
any purchase today should definitely consider quad-core cpus.
