This palm-sized i9 mini PC now lives by my router — and my AI agents run it

When people picture a powerful PC they picture a big tower with RGB and a huge GPU. I wanted to see how much of that you still need, so I got the KAMRUI Hyper H2: a Core i9 mini PC that fits in my palm. It ended up on a shelf next to my router, and my AI agents do most of the driving.

Tiny, and lighter than I expected

This is the Silver Hyper H2 with 32GB of RAM and a 1TB SSD. It came very well packed, and the first surprise was the weight: it is much lighter than it looks. The body feels solid, although the top panel turned out to be plastic, not the metal I assumed. There are cooling fins around the edge and a fairly big fan inside.

The box says the same thing twice: do the first setup offline, with no Wi-Fi and no LAN, so Windows doesn't get stuck pulling updates halfway through setup. They even put a sticker over the port to make the point.

Ports and what's in the box

On the back you get DC in, HDMI, a LAN port and four blue USB-A ports. The front has one USB-C (I'm glad there's at least one), two more USB-A ports, an audio jack and the power button.

In the box: the power brick, a long power cable, an HDMI cable, a user manual, and a wall-mount bracket with screws. The PC is small enough that hanging it on a wall or under a desk is realistic. The brick is rated at 120W, which is chunky. My MacBook Pro's charger is about 100W.

It lives next to my router now

I don't have desk space for another machine, and I didn't want another monitor. So the mini PC sits on a shelf next to my router and an old DVR, which it is smaller than, plugged in over Ethernet.

My main setup is a MacBook Pro on a 49-inch Samsung Odyssey G9. When I need Windows, I open Remote Desktop on the Mac and the mini PC is right there, on the same screen, keyboard and mouse. Windows 11 Pro came activated, which is why Remote Desktop was available without extra work.

My AI agents run it over Tailscale and SSH

This is the real reason I wanted it. I installed an agent on the mini PC and used it to set up passwordless SSH and Tailscale's MagicDNS, so my Mac and the Windows machine can always find each other.

Now all of my agents can reach it. When I asked one to check the Windows PC, it ran a health check over Tailscale and SSH and came back with CPU load, free RAM, free disk space, and whether the Android emulator and Gradle were running. I'm a mobile developer, so that's exactly the kind of build worker I wanted. Closing Remote Desktop doesn't affect the agents; they keep working on their own. I also shared folders between the two machines so copying files across is easy.

The specs, and the one real gap

In Windows' About screen: an 11th-gen Intel Core i9-11900H at 2.5GHz, 32GB of RAM at 3200 MT/s, and a 954GB SSD with most of it free.

The biggest gap is graphics. There's no discrete GPU, just Intel UHD Graphics, so this is not a gaming machine. The i9 is also a few generations old; newer chips are better. And 32GB is plenty, but I would have loved 64GB. You get what you pay for, and for a build machine it's the CPU, RAM and SSD that matter to me.

Who should buy

If you mostly work on a Mac and want a small Windows box you can tuck away and reach remotely — as a build worker, home server or backup machine — this makes a lot of sense. It's my first mini PC, and it was far less hassle than I expected.

If you want to game, edit heavy video, or need the newest CPU, look for a mini PC with a discrete GPU instead.
