Dell PowerEdge T110 II (Xeon E3-1220v2, 4GB RAM, 500GB) $432.84 + tax + FS
Default config is:
Intel® Xeon® E3-1220v2 3.10 GHz, 8M Cache, Turbo, Quad Core/4T (69W)

I upgraded my config to the E3-1230v2 for $38.44 which bumps the PassMark score from 6742 to 9051. That is the price/performance sweet spot for this particular deal. Another upgrade worth considering is the 1TB drive for $20 extra.
Starting price is $602.84 but coupon $ZG1V$CLGM6R0Z takes $170 off for a total of $432.84 shipped + options + tax.
Mine will get a RHEV 3.2 install and sit next to my T110 running ESX 5.1
