Got my mining rig back from @Coriolanus (thank you for babysitting). Plugged it in and it was up and running within minutes. It's been running so well I don't even have a monitor nearby for troubleshooting. I should still be able to access it through my network but I've been happy with the output of zcash over the last few months.
I don't really optimize for power since I'm more concerned with output. I should probably be aiming for at least 100W lower. Besides a very shitty rack, I'm quite happy with this rig.
I've been making some extra money this past month and have been considering expanding my mining empire. I have about $2000 in BTC right now and I could double the size of my mining rig with that (or pay off some bills). I won't be making any decisions until next week and will be weighing my options over the weekend.
More crypto or more debt? That is the question.
