No, I did not count my labor. It is true that capex and opex of mining gear is well-known and can be calculated so as to be profitable in and of itself. However knowing how to manage all the other costs (labor + capex on the DC itself) is what distinguish good mining companies from bad ones. IMHO these areas is where KnCMiner made the biggest mistakes. Just compare a picture of a KnCMiner DC vs. a Chinese DC and you will see KnCMiner did not try hard to build cheap DCs...
