i got my hands on the following gear

Dual Xeon 5645 ("nehalem cpu")
2.4ghz- 2.67GHX
6cores with hyperthreading
total 24 execution units

It comes with with 48gb registes eec ddr3 ram (24gb for each cpu)
it also has a couple of 4x 10gbe ports and 8x 1gbe ports but no storage units

I have to jerryrig a power supply for it but im pretty confident in doing that.
my price is 75$ maybe even way lower
its mainly going to be used for 7-zip compression. x.264 encoding and png optimizing (takes forever)

Go for it or no ?
