The list price of a Myrinet-10G card with a CX4 port is $695 (From 
website).

The cable will run you about $100 (depending on source and length).

I found a price for the 48-port 3Com 3870 with 10GBASE-X module
and CX4 transceiver for about $4800 (www.costcentral.com).  The
switch says it is layer-3 capable, but I don't see if that is
a part of the 10BASE-X module or a separate cost.

I didn't think it was that cheap.  I would prefer Layer 3 if
this was going into a rack of a multi-rack system, but the
price is right.
