I'll 2nd the Aberdeen recommendation.  I'll add Pogolinux to that list as well.

The 2 best performing RAID controller vendors at this time are AMCC
(AKA 3Ware) and Areca.
In general, the 8+ port Areca's with their BB cache maxed outperform
every other controller available.

Be =very= careful to thoroughly bench both the AMD and Intel CPU
options.  It is far from clear which is the better purchase.

I'd be very interested to see the results of your research and
benchmarks posted here on pgsql-performance.
