I am participating in PoM with:
1. Dell Poweredge C6100 server I got from eBay with 4 nodes and two 4 core Intel Xeon L5420 CPUs per node. Hash rate per node=~70 Kh/s
Here is the cpubenchmark.com comparison for the Dual Xeon L5420 compared to other CPUs:
https://cpubenchmark.net/cpu.php?cpu=Intel+Xeon+L5420+%40+2.50GHz&id=1259&cpuCount=22. Dell Poweredge C6105 server (eBay) with 3 Nodes, and two 6 core AMD Opteron 2419EE (North Bridge) variety. Hash rate per node=~77Kh/s
Here is the cpubenchmark.com comparison for the Dual AMD Opteron 2419EE compared to other CPUs:
http://www.cpubenchmark.net/cpu.php?cpu=AMD+Opteron+2419&id=1858&cpuCount=2Current hash rate on nonce-pool for these two servers combined is 556.61 KH/s.
One server draws at max load about 450 watts for 4 nodes. For 3 nodes it will be less than 450 watts.
I was previously mining ducknote with these, here is the YouTube video I made:

Counter-intuitively, the AMD Opteron CPU is cheaper but hashes quicker on M7M algo.
The more expensive Xeon CPU will hash quicker on cryptonight algorithm than the Opteron CPU (as expected).
*** JoeLao the 3-node Dell Poweredge C6105 is dirt cheap looks junky on the outside (refurbished of course) but it works good, if you need a spare development server.
Here is the eBay link they still have a ton of these (48GB RAM total, so 16GB Ram/node, comes with 3 250GB HD one for each node) ***:
