My company has 4x of a simmilar product in our 3d render farm, speaking from experience, avoid these at all costs.  If we did not have as much $ invested in them as we did, I would have ditched them long ago, they are an IT nightmare.  In most cases, its a downtime issue that with mining will start adding up to some serious BTC, in other cases we had hardware itself go bad that required painful support processes to get fixed.
