For $6,500 each, I was able to build 4-way 2.3 GHz 8 core Opteron
machines with 64 GB of ram. I started with a Supermicro barebone
AS-2042G-6RF.

And added CPUs

and RAM. The nice thing about the Supermicro barebones is that the come
with the heat sinks, so all you need to do is drop in the CPUs and ram,
and you are ready to go.
I went with 2U instead of the 1U because it was all I could get at the
time. If I was doing it now, I'd probably go with the 1U to save $500 a
node. You might save some money by going with less ram, but you will
still need a lot of sticks because the board needs to be populated in
multiples of 4. These things are very loud. I would not want to work
in the same office with one under full load. Hide it in a closet and
you should be ok.
You will have a hard time finding a typical "PC" type setup for this
because the 4-way motherboards have a unique form factor and are larger
than EATX. Last summer I was looking for a chassis to fit such a
board and gave up. Much easier to go with the motherboard/chassis combo.
Regards,
Jeff
