Thanks for all the input.  I checked through all of them but since the recent spike in interest crypto, everything is out of whack right now.  I have decided short term to focus on running ethereum nodes to get gain experience in anticipation of POS. Also, in the future, maybe SOMN (seems to be having issues) or something like SOMN.  I will also try to set up some file sharing services to squeeze out every last bit from my rigs.  Thanks again everyone.
