You might check with Silicon Mechanics as they build a lot of
Supermicro boxes with 3Ware cards.  I have a couple of 2U boxes
here that I'm preparing to deliver to a customer which have them.


You may be able to find Supermicro parts on eBay as well.  I have
a 2U server here that I got on eBay which is working nicely.
