One thing to consider before doing the same, a computer done for homelab has a much lower consumption. The setup mentioned in the article has an avg 600 kWh/year as opposed to a pretty solid HP EliteDesk (my own homelab) which uses 100 kWh/year. Sure you don't get a GPU but for what it is used for, you might as well use a laptop for that.

Could also use Cloudflare tunnels. That way: 1. your 1password gets a different entry each time for . . 2. you get https for free 3. Remote access without Tailscale. 4. Put Cloudflare Access in front of the tunnel, now you have a proper auth via Google or Github.
You can also use cloudflare to create a dns record for each local service (pointed to the local IP) and just mark it as not proxied, then use Wireguard or Tailscale on your router to get VPN access to your whole network. If you set up a reverse proxy like nginx proxy manager, you can easily issue a wildcard cert using DNS validation from your NAS using ACME (LetsEncrypt). This is what I do, and I set my phone to use…
>Because all of my services share the same IP address, my password manager has trouble distinguishing which login to use for each one. In Bitwarden they allow you to configure the matching algorithm, and switching from the default to "starts with" is what I do when I find that it is matching the wrong entries. So for this case just make sure that the URL for the service includes the port number and switch all items t…
Then, I use Tailscale to connect everything together. Tailscale lets you use a custom DNS, which gets pointed to the PiHole. Phone blocks ads even when im away from the house, and I can even hit any services or projects without exposing them to the general internet.
Then I setup NGINX reverse proxy but that might not be necessary honestly

Just giving them hostnames is easier. In homelab space you can also make wildcard DNS pretty easily in dnsmasq, assuming you also "own" your router. If not, hosts file works well enough. There is also option of using mdns for same reason but more setup
> Just giving them hostnames is easier Bitwarden annoyingly ignores subdomains by default. Enabling per-sudomain credential matching is a global toggle, which breaks autocomplete on other online service that allow you to login across multiple subdomains.

I invoke backups from a systemd timer. If the schedule is missed (due to sleep, power off etc.) it runs it at the next earliest opportunity.
How does it handle restart after the machine wakes up again?

Cheap to buy old hardware, but electricity to run those old rigs isn't really cheap in many areas now. My server is costing me about $100/month in electricity costs. It does have 16 spinning disks in it, so I accept that I pay for the energy to keep them spinning 24/7, but I like the redundancy of RAID10, and I have two 8-disk arrays in the machine. And a Ryzen-7 5700G, 10gbit NIC, 16 port RAID card, and 96GB of RAM.
How have you measured the power usage/cost? That seems like a incredibly high price for electricity, similar to a 600W constant load in my part of the world.
I do have a bit more than just that server hooked up to it. There's also a Dell i5 running DDWRT as my main gateway/router, the fiber internet modem, a small Synology NAS, a couple of WIFI routers, etc. It all adds up.
That doesn't include my backup server out in the garage with another 8-disk RAID10 array and an LTO tape drive that is often backing up data, 5 more WIFI routers around the property, and 10 or so security cameras. So I'm probably well over $100/mo for all my tech stuff.

I’ve been watching some storage and homelab-themed videos and I heard there’s a lot of optimizations you can do to lower power usage - spinning the disks down, turning the machine on for a limited time, etc.

When the machine wakes up, systemd checks the timer's schedule and when it last ran. If one or more runs were missed due to the sleep, it's executed immediately.
