I don't know if a CPU rig is possible or profitable, but this clearly means that someone found a way to mining lots of ROI
(GPU ?)

That's not a lot of hash rate we know one guy who can do 100kH/s with a special intel polaris chip

A single Dual AMD Epic server can probably already do 10kH/s , but why would you use such expensive gear.
