PiHole!

One of the easiest installer I've ever seen. Significantly less ads to be shown especially one on non-browser.

Wait, where's "Waifu" flare?

Great shot BTW

For me, at least, is a custom CNAME DNS record. I've both internal (point to device directly) and external (via reverse proxy) domains. I use a CNAME record to point the external domain back to the internal one for my local split DNS. Technically it can be applied on Adguard; not as easy as PiHole though.

Not too shabby TBH. Still have a concern about the storage thought. Since PN52 can only have 2 SSDs and 1 HDD, RAID is out of questions.
