Sorry, I missed a couple of the additional questions.

Yup, I wish it were possible to use registered dimms on 3500. :(

As long as it can fit in the case with a basic riser board. Unfortunately
the case has a PCI-X not PCIe riser board right now.

We already have 4x 1.5T drives in RAID

We already have an 80Plus PSU in the system. The current machine uses
about 130W. I figure we can get that down to 70-80W by upgrading to a
newer board and CPU, but we have 4 drives, it's not going to get that much
better. This won't save that much money tho. 50W is only about
$6.50/month. It'd take 8 years for that to pay back just in power. This
is one of the reasons why I think it's worth just keeping one server
around the space. Mostly I want this upgrade so we can do more with the
box than just run pony.
I have alread found a replacement 2U case for the machine that will work
great. It should have a good quality PSU in it, but I can double check
the specs some time.
If not, this should probably fit in the case:
I think we should go with the revised intel proposal:
SUPERMICRO MBD-X9SCL+-F - $180
Intel Xeon E3-1230 Sandy Bridge 3.2GHz - $240
2x Crucial 8GB (2 x 4GB) - $160
1U CPU cooler - $25
Total - $605
Not too expensive, and should get us to a power target of ~80W without
being slow as crap.
