I need to rebuild a moderate horsepower unRAID server without breaking the bank or electric bill.  I require a minimum four PCIe 3.0 slots and 28 lanes.  That means I have to go socket 2011 and a 40 lane Xenon (40 lane i7 cost too much).  I also need IPMI.  32GB RAM and a CPU cooler that fits in a 4U rack case without sounding like a jet engine.  I will be using Adaptec 71605Q maxcache controllers, so mobo SATA is irrelevant.

 

I also want a CPU higher in clock speed rather than more cores since a couple of my main apps that will run on this system benefit much more by higher clock speed than more cores/threads.

 

I am leaning toward the ASRock EPC602D8A with a Xenon E5-1620 and Cooler Master Gemini II cooler (replacing the fan with a high static pressure fan, like an Akasa Viper (3.12 mm H2O) or Cooler Master Excalibur, with a shroud).  RAM is to be 2 sticks of KVR18R13D4/16KF.

 

MoBo:ASRock EPC602D8A

CPU:Xenon E5-1620

Cooler:Cooler Master Gemini II

RAM:KVR18R13D4/16KF

 

Comments or suggestions?

 

BTW, I am still waiting for conformation from CM that the Gemini has a bracket for the narrow LGA 2011 mountpoints.  If not, I am back to the drawing board on a mobo.

The Gemini cooler does *not* have a bracket for a narrow LGA 2011 so the CPU cooler will have to be Noctua NH-U9DX i4 or NH-U9DX i4 3U.

 

Another potential mobo is a  Supermicro MBD-X10SRI-F.

 

Any comments on the Supermicro MBD-X10SRI-F vs. the ASRock EPC602D8A

You ever think of getting one of the ebay xeon E5 ES V3 or V4 for around $200?

No, because as the OP noted, I need clock speed more than cores.  The E5-1620 gives me 3.5gHz w/o paying for unnecessary cores.
