Buy a whatever and turn off all but two cores on the kernel command
line.

max_cpus=2

You want an Intel LGA1366 chip with an X58 chipset; 32 PCIe lanes are
available.  (If you were asking this question 1Q2012, the LGA2011 would
become preferable -- 40 lanes of PCIe v3.)

For I/O, you might want to look at an on-PCIe SSD, like the FusionIo
cards. Expensive, yes -- but compared to the SAS license, probably not
so bad. And the performance is amazing, if you can fit your
current dataset.
