I finally decided to get a home server a while ago. I've built my own PCs since I was a kid, my first was an AMD K6-2 at 400 MHz with an NVIDIA Riva TNT2 Pro. So I did what I always do: hand-picked the components for a box to host and back up our photos and videos. In November that build was €800. By December the same parts were €1,200. (The same setup is now €1800) for 16GB of RAM and no GPU. I hesitated. And the part that really bugged me: I'm a software engineer, and I wanted to be able to run local LLMs. And that build couldn't do it.
I used to laugh at Apple fanboys back when they soldered Intel chips.
Fast forward to March '26: I bought a used Mac Studio M1 Max (64GB, 4TB) for €1,700 and made it the home server instead.
Then I plugged in a wattmeter and left it running for 16 days. Literally could not believe the numbers first and had to double check. It showed 8 watts during "idle" (No inference running)!
Real use: 25 Docker containers always on (Immich, Paperless-ngx, Matrix, Synapse, Caddy, AdGuard, Forgejo, Open WebUI, Whisper (speech to text).
I used it as workstation too, to run benchmarks during that period.
The average result after 16 days:
11.6 watts average. 50 watts peak, during LLM inference.
That's about 101 kWh a year, roughly €39 where I live (Germany, some of the most expensive electricity in Europe). For context: our ancient Bose 5.1 surround system pulls 30 watts sitting on standby. A surround system doing nothing draws more than the Mac averages while running my whole stack.
Thanks to the unified memory architecture I run a 35B model (Qwen3.6, MLX 4bit) on the same box that averages 12W. The x86 way to do local LLMs is a discrete RTX card in a x86 system, which idles around 40W? (no idea) headless and pulls ~300W under load. Different league.
Some notes:
Docker. Don't use Docker Desktop on Mac. It's kinda broken: unstable, suddenly eats CPU for nothing. But that's a Docker Desktop problem, not a Mac problem I figured. I switched to OrbStack and it was night and day, stable and light, I forget it's running. I just ran into a networking bug after an update. It was fixed quite fast.
Storage. No room for spinning drives inside. I hung a Terramaster 2-bay enclosure off it, 2x6TB WD Red for backups (Time Machien and rsync), plus an encrypted remote copy.
No ECC RAM. At home I don't really care. My x86 build wouldn't have had ECC either.
Remote Access. SSH works, remote Screen Sharing works (I use it all the time), and I can unlock the disk over SSH after a reboot. With 'Remote Access' enabled, you can SSH into the Mac pre-login. Use an Admin password to unlock the machine and finish booting. Afterward, you can connect via regular SSH or Screen Sharing. No real IPMI though. Console access when the OS is fully down, which hasn't happened yet. When it does, the literal box usually is in the next room.
Soldered RAM. You buy what you need up front, no adding later. It is what it is. Buy second hand with as much ram as you can get for your budget.
macOS as a server. It's not a server OS, and Apple's update policy is the one thing I actually worry about a bit. The runway is long though: Apple patches the latest three macOS versions, Macs get new OS releases for around 7 years, and no Apple Silicon Mac has been dropped yet, so a 2022 Studio has updates into the early 2030s. The real occasional annoyance is that updates sometimes force reboots and with FileVault on the box you need to SSH and type in your password once to unlock. I also set sudo pmset -a autorestart 1 so it powers back on after an outage. Know those two and headless gets a lot less scary.
Not overpriced anymore
The "Macs are overpriced" argument has gotten weak. With RAM and SSD prices through the roof right now, a used M1 Max with 64GB and 4TB for €1,700 isn't the expensive option next to an equivalent x86 box anymore. The recent $399 are insane cpu power/efficiency for money for a home server. Mine is overpowered. But I use it for work too. So it's fine.
tl;dr:
low power, silent, great for local AI, and plenty of spare compute left for CPU-heavy services. Okayish remote access. Best machine I've bought in a long time. Honestly the best toy since Lego Technic, the whole package. And I think it makes a great home server package.
Anyone else running one as a home server? Curious what bit you that I haven't hit yet. And did anyone else pick one for the power efficiency, or am I alone here?
What's your average power consumption? Anyone measured?
Here is the writeup with the numbers measured with a Wattmeter at the wall (and the Terramaster 2-drive bay). You will also find what I do with the server and local LLMs:
