I've not played with PiHole yet, but other products like it. My understanding is this. Your Router itself should still use the Public DNS for it's calls. That's how it still sees the internet. Your DHCP server (which is probably a different section in your router) should be updated to hand out the PiHole IP as DHCP. What that does is tells any of your devices connecting to the router "Use PiHole to reach the internet", just like you said works when you manually set on your end device.

Will be following your post with interest. My existing server build is almost identical (except I went the Celeron route). Also have a separate server for my Plex at the moment, and would love the hardware power to merge them into one box.

Thanks DoeBoye! I've been having exactly the same symptoms out of my Norco case, and was suspecting either Backpanes or Controller Cards. Your thread was the first I started suspecting power. Looking inside, I had one of those 1x7 molex adapters, and was essentially running everything off of one PSU lead. And now that I'm looking, it was the Backpanes with the most non-green drives attached that we're the biggest offenders. Spreading out my heavy drives to separate backpanes, and have ordered some sata to molex adapters to help bulk up my power input leads. Happening once in a blue moon, I can handle. Lately it had been wiping out every time I run Parity Check, and I've since just powered down until I had time to look into it.
