I use a Synology DVA 1622 NAS to host all of the things you did. The only difference is I upgraded the RAM to 16 GB (to handle my other services)
My wife and I can watch high quality series at the same time with no issues. Only limiting factor is our WiFi connectivity in the house is shit.
Mine is a bit exotic I guess. I use Terraform to manage my home lab. I tried all of the docker update solutions out there and they'd always make my Terraform out of sync. So I built my own solution that interacts with an orchestrator, a backend and a front-end.
I use Terraform to create flows for each service. Then the flows interact with the backend to manage the actual updates. The frontend is there to let me see the latest change log of each project before I update.
For my next project I want to set up an oil tank monitor for our heating. Then I can use Prometheus and Grafana to monitor usage. From there I can start making predictions and so on
Right now it's private only and basically a V1 home version. I'm planning to rewrite it to make it public.
Long term I want to write terraform resources directly to my backend and take out the orchestrator.
