The Homebrew AI Agent Starter Kit — Gear I Use to Run Hermes 24/7

You’ve seen the videos. You’ve watched me talk about OpenClaw vs Muse, about the gaps and the bridges. But the question I get most is: what hardware do you actually run this on?

So here it is. The exact gear I use to run Hermes — my self-hosted AI agent — 24 hours a day, 7 days a week. No cloud subscriptions, no monthly fees. Just hardware you buy once and forget about.

The Brain: Apple Mac Mini (M1)

This is the heart of the operation. My Hermes agent lives on a 2020 Mac Mini with the Apple M1 chip. 16GB of RAM, 256GB SSD. It sips power — about 7 watts at idle — which means I can leave it running 24/7 without thinking about the electric bill.

The M1 is a sweet spot: fast enough to run local inference on smaller models via llama.cpp, efficient enough to never need active cooling, and cheap enough on the refurbished market to be a no-brainer.

Why not a Raspberry Pi? You can run lightweight agents on a Pi 5, but the moment you want browser automation (Playwright), local models, or anything involving video processing, you’ll hit the memory wall hard. The Mac Mini is the floor, not the ceiling.

The Insurance: APC Back-UPS 600VA

Nothing kills a homebrew agent setup faster than a power blip at 3 AM. The Mac Mini is robust, but a sudden power loss during a write operation can corrupt files. Ask me how I know.

The APC Back-UPS 600VA gives you about 15-20 minutes of runtime on a Mac Mini — plenty of time to ride out a brownout or shut down cleanly. It also conditions the power, which matters if your home wiring is older.

Seven outlets: five with battery backup, two surge-only. I plug the Mac Mini, the router, and the smart plug into the battery-backed outlets. Everything else can flicker off.

The Remote Reset: TP-Link Kasa Smart Plug

This is the single most useful piece of gear in my entire setup. The smart plug.

Look — agents crash. Web gateways hang. Software updates go sideways. And if you’re running headless (no monitor, no keyboard), getting back in requires either walking to the machine or having some kind of remote power control.

The Kasa smart plug lets me cut power and reboot the Mac Mini remotely from my phone. When Hermes goes unresponsive and I’m not at home, I open the Kasa app, toggle the plug off, wait ten seconds, toggle it on, and the Mac boots fresh.

I’ve used this feature more times than I care to admit.

The Storage: Samsung T7 Portable SSD

Two hundred fifty six gigabytes fills up fast when you’re running an agent workspace. Log files, downloaded YouTube thumbnails, rendered video drafts, model weights, browser caches — it adds up.

The Samsung T7 is my overflow drive. 1TB, USB 3.2, reads up to 1,050 MB/s. It’s fast enough to run the agent workspace off directly — I’ve done it — but I mostly use it for media storage and model weights.

AES 256-bit hardware encryption means if the drive ever walks off, the data stays contained.

The DIY Expansion: NVMe USB-C Enclosure

If you have spare NVMe drives from a laptop upgrade (and who doesn’t), an NVMe enclosure turns them into usable external storage. I run a Sabrent EC-SNVE that does 10Gbps over USB-C, and I swap drives depending on what I’m working on.

One drive holds model weights for local inference. Another holds workspace backups. A third holds video assets.

The Alternative Brain: Beelink EQ12 Mini PC

Not everyone wants a Mac Mini. If you’re coming from Windows or Linux and want to run OpenClaw directly without macOS in the picture, a Beelink mini PC with an Intel N100 processor is a solid alternative.

The N100 sips power (6 watts typical), supports up to 16GB of DDR5 RAM, has dual Ethernet (useful if you’re also running a router or firewall on the side), and costs about $160-200. It handles Playwright browser automation comfortably and runs Ubuntu or Windows 11 Pro without complaint.

The Port Expander: Anker USB-C Hub

The Mac Mini M1 has two USB-C ports and one HDMI. That’s it. When you’re connecting an external SSD, a keyboard dongle, and maybe a monitor — you run out fast.

The Anker 332 USB-C Hub gives you 4K HDMI, a USB-C data port, and two USB-A ports. It’s small enough to live behind the Mac Mini permanently.

Putting It Together

Here’s exactly what my desk setup looks like:

1. Mac Mini M1 (always on) → plugged into APC UPS → plugged into Kasa smart plug
2. Samsung T7 SSD → plugged into Mac Mini via USB-C
3. Anker USB-C Hub → plugged into Mac Mini’s second USB-C port
4. Spare NVMe drives → swapped via the Sabrent enclosure as needed
5. The Beelink — sits on my shelf as a spare/test rig

Total cost (one-time, not monthly): About $600-800 depending on whether you already have the Mac Mini. Compare that to a year of Muse at $240 — and you own the hardware.

The Bottom Line

A self-hosted AI agent needs three things: a brain (the computer), insurance (the UPS), and a reset button (the smart plug). Everything else is expandability.

I built this stack once. It’s been running for months without a subscription renewal, without a feature gate, without Meta deciding my integration is no longer supported. When something breaks, I fix it. When I want more storage, I plug it in.

That’s the whole point of the homebrew approach. You own the stack. And when you own the stack, nobody can take it away from you.
