thanks for sharing it but aren't the opteron cpu better in price/hasharate
Yea but they are power hungry.
But you can buy a new socket G34 4 cpu motherboard for under $80.00 of course you would have to deal with non standard format and non standard power connectivity and every time I thought of it I quickly talked myself out of it.
The more standard boards are more expensive to the point its not worth it.
It's worth doing if you could get a deal on a decommissioned server for cheap.
But you can purchase a dual node dual cpu open compute socket 2011 Wiwynn server new in the box for under $200.00
http://www.ebay.com/itm/Wiwynn-SV7210-Two-Node-Open-Compute-Server-Dual-LGA-2011-/391296440423All you need to do is buy 4 cheap E5-2600 V1 cpu's and some cheap ddr 3 ram and a SSD and 240 volt power source, will run Linux and windows 7 just fine.
The only reason I have have not bought several is I moving away from socket 2011 and moving to socket 2011-3.
EDIT: Every time I look at those open compute servers I am SO tempted........I must not buy.........must not........will power must have will power.....LOL
