Can do.

At this time I'm looking at;

Dual Sforza CPU
LSI 8i SAS card
4 8GB RAM modules

I was thinking about the Microsemi SAS controller but after some email exchanges with Raptor it turns out that chip uses proprietary firmware/microcode and the LSI board has open drivers.

As for all the RAM. The system works best with each CPU having its own RAM. It could be 1 8GB module for each but according to Raptor the performance gain with 2 modules per CPU is amazing.

Since I won't be running any kind of server or tracking asteroids in other galaxies the 4 core CPUs should be more than enough for any desktop type usage.
