Full-o-ram and E5-2650L v1 cpu's.
Samsung ecc pc8500 4gb sticks and cpu's for cheap.
The 2650L v1 cpu's were right at 20.00 each shipped, wanted the most cores with the lowest tdp at the cheapest prices I could find.
Not looking for cpu's that will turn my house into an oven like the 2665's I had and these run pretty cool.
The ram ended up costing me $.63 per GB.
EDIT: I just bought some even cheaper pc8500 ram at $.32 per GB, just love "Make Offer" listings.
That's $1.25 per 4 GB stick of ram, its nice having so many ram slots that I can fill with cheap 4gb DDR3 instead of pricier 8 GB. 64 gb per node will be plenty for now.
