Did you take increase in electric bill into account? When I set up a similar one it was barely enough to offset electricity. I did some Ethereum mining early on and gained a few coins actually, but I stopped a while ago as it reached a point where I wasn't making enough with the expense to justify it anymore. I probably just need a newer and more efficient rig, but you need to take that into account.Okay, so here's my new hash rate and earnings since about 30min ago
I'm now very seriously thinking of building a dedicated mining rig.
