Pihole has not blocked YouTube ads for probably 5 years now.

Brocades definitely have a risk of dying after a year, I’ve got 2 6450s with about a dozen ports that only negotiate 100M now. Still nice switches though.

Just run split DNS. Set the same records on your Pi-hole, and they will be used first over external records in Cloudflare. You can go as far as setting a wildcard that points every record under *.domain.com to your reverse proxy (manual entries will override this wildcard) and you will then just have to add an entry point to your reverse proxy and they’re ready to go.

Use your computer as a seedbox if they haven’t installed a virus on it already.
