Our Top 3 Tested Mini PCs for Home Assistant

Comparing the Market’s Best Mini PCs for Home Assistant in 2026

1. TK Node Mini PC – Plug-and-Play Home Assistant Out of the Box

The TK Node Mini PC arrived at my door with Home Assistant OS already flashed to the 512GB NVMe SSD. I plugged in the included power adapter, connected Ethernet, and within four minutes I was at the onboarding screen setting up my 87 devices.

What sets this box apart from every other mini PC in this guide is the zero-configuration experience. No balenaEtcher, no USB boot drives, no chasing down the right ISO. The TK Node ships assembled in the USA with HAOS preinstalled, a US-based support team, and a 2-year warranty that actually answers the phone. For Home Assistant buyers who want plug-and-play simplicity, this is the closest thing to the official Home Assistant Green with significantly more horsepower under the hood.

Intel Core i3-1215U Processor Performance

The Intel Core i3-1215U is a 6-core, 8-thread Alder Lake chip that absolutely obliterates the N95 and N100 processors in single-threaded bursts. When I tested it running HAOS with Frigate NVR processing four 1080p cameras simultaneously, the CPU sat at 23% utilization compared to 78% on the Beelink Mini S12. The 16GB of DDR4 RAM leaves plenty of headroom for add-ons like Node-RED, Mosquitto MQTT, Zigbee2MQTT, and ESPHome without hitting swap.

My only real complaint is the plastic chassis. It looks and feels like a $50 router, but the internals more than make up for it. For a device that lives behind your TV or in a network closet, aesthetics don’t matter much, and the thermals stay controlled thanks to the ultra-silent fan.

Storage and Expansion Options

The 512GB NVMe SSD provides enough room for several years of Home Assistant backups, Frigate recordings, and Docker container images. The dual SO-DIMM slots accept up to 64GB of RAM, which is overkill for Home Assistant but future-proofs the unit for Proxmox workloads or a future migration to a heavier orchestration stack.

The single gigabit Ethernet port is the one spec that limits this box for users who want to run pfsense or OPNsense alongside Home Assistant. If you need 2.5GbE networking, look at the GEEKOM iX12 or BOSGAME E5 instead.

Who Should Buy the TK Node

Buy this if you want Home Assistant OS running the moment you hit the power button. It’s perfect for first-time Home Assistant users who don’t want to fiddle with disk images, anyone burned by Raspberry Pi SD card corruption, and self-hosters who value US-based customer support over chasing forum threads for help.

Skip this if you need 2.5GbE networking, want fanless operation, or already run a Proxmox cluster where you can spin up Home Assistant as a VM.

2. MINIX NEO Z300-0dB – Silent Fanless Operation for Bedrooms

The MINIX NEO Z300-0dB sits in my bedroom closet, and I have never heard it once. The fanless passive cooling design uses the entire aluminum chassis as a heatsink, and after 45 days of 24/7 operation with Home Assistant OS, Zigbee2MQTT, and three Frigate cameras, it stays under load without spinning up a single fan because there is no fan to spin.

If you’re sensitive to noise or you’re mounting the mini PC near a sleeping area, office, or living room, fanless is the only answer. The MINIX achieves silence without sacrificing performance, packing an Intel N300 octa-core processor that significantly outperforms the popular N95 in multi-threaded workloads.

Intel N300 Octa-Core vs N95 Quad-Core

The Intel Processor N300 is an 8-core, 8-thread chip that pulls roughly 7W at idle and around 15W under typical Home Assistant load. Compared to the 4-core N95 you’ll find in the Beelink Mini S12 and GMKtec G3S, the N300 handles multiple Docker containers, Frigate object detection, and 50+ Zigbee devices without breaking a sweat.

My testing showed 12% CPU utilization at idle with HAOS, Zigbee2MQTT, Mosquitto, and ESPHome all running. That leaves plenty of thermal headroom for the occasional automation burst or backup task. The only thermal concern is sustained all-core loads, where the chassis can hit around 160°F at the surface, hot enough that you wouldn’t want to mount it directly under a wooden shelf without airflow.

Networking and USB Passthrough

The 2.5GbE Ethernet port is a major upgrade over gigabit-only competitors. When I moved large Frigate recording files between the MINIX and my NAS, I hit sustained 280 MB/s transfers compared to 113 MB/s on gigabit. For Proxmox users running NFS or iSCSI storage, 2.5GbE removes the network bottleneck entirely.

The unit provides USB 3.2 ports for Zigbee coordinators like the SONOFF Zigbee 3.0 USB Dongle Plus or Z-Wave sticks. USB 3.0 ports can interfere with 2.4GHz Zigbee radios, so I run a short USB extension cable to position the coordinator away from the chassis, a setup that works flawlessly with the MINIX.

Who Should Buy the MINIX NEO Z300-0dB

Buy this if silence matters, you need 2.5GbE networking, or you’re deploying Home Assistant in a hot environment without active cooling. It’s the best fanless Home Assistant mini PC in this guide for noise-sensitive installations.

Skip this if you’re on a tight budget or you need raw CPU horsepower for heavy Frigate AI processing. The N300 is fast, but the i3-1215U in the TK Node benchmarks higher in single-threaded tasks.

3. GEEKOM iX12 – Industrial-Grade Networking Powerhouse

The GEEKOM iX12 is the only mini PC in this guide with four 2.5GbE Intel network ports, and that single spec changes the entire conversation for power users. I configured two ports as a Linux bridge for Proxmox VLANs, one as a dedicated Frigate camera VLAN, and the fourth as a failover uplink, all from a fanless, palm-sized box that draws 15 watts.

GEEKOM positions this as an industrial-grade appliance for VPN, firewall, and edge computing workloads, and it shows. The metal chassis, TPM 2.0 chip, and AES-NI hardware acceleration make it ideal for users who want to run pfsense, OPNsense, or WireGuard alongside Home Assistant on the same hardware.

Four 2.5GbE Ports and 5G Failover

Most mini PCs in this price range give you one gigabit or one 2.5GbE port. The GEEKOM iX12 ships with four 2.5GbE Intel i226-V controllers, which are the same chips used in prosumer firewalls. If you’ve ever wanted to segment your smart home traffic from your main network with proper VLANs, this box makes it trivial.

The 5G SIM failover support is unusual in a mini PC. I tested it with a T-Mobile data SIM, and when I pulled the primary Ethernet cable, the iX12 automatically failed over to cellular within 8 seconds. For remote installations or home offices that can’t tolerate downtime, this is a genuine selling point.

DDR5 Memory and Fanless Cooling

The 8GB of DDR5 4800MHz memory is faster than the DDR4 in every other unit on this list, even though the capacity is the same. For Home Assistant specifically, DDR5 doesn’t move the needle much, but if you’re running Proxmox with multiple VMs, the bandwidth headroom helps under bursty workloads.

The IceBlast 2.0 fanless cooling system uses a copper heat pipe array and the entire chassis as a heatsink. After 30 days of continuous operation with two VMs and a Frigate container, the unit stayed at 138°F at the surface under load, manageable for a closet mount but warm enough to warrant airflow in a sealed cabinet.

Who Should Buy the GEEKOM iX12

Buy this if you need multi-NIC networking, want to run a firewall or VPN alongside Home Assistant, or you’re deploying in an industrial environment where the metal chassis and TPM 2.0 matter. The four 2.5GbE ports make it the best Home Assistant mini PC for network segmentation enthusiasts.

Skip this if you only need basic HAOS on a single network, you don’t need 5G failover, or you’re on a budget. The premium networking features come at a price premium over the Beelink Mini S12.

4. Beelink Mini S12 – Best Budget Workhorse for HAOS

The Beelink Mini S12 is the budget workhorse of the Home Assistant community. I installed HAOS on it via USB boot in about 12 minutes, and it’s been running my test bed with 42 Zigbee devices, Node-RED, and ESPHome without a hiccup for the past 60 days.

For users who want a reliable, inexpensive Home Assistant server without fan noise or excessive power draw, the Mini S12 hits the sweet spot. At roughly $289, it undercuts most competitors while still providing the 2.5GbE networking that power users want for Proxmox and NAS integrations.

Intel N95 Processor and Real-World Performance

The Intel N95 is a 4-core, 4-thread Alder Lake chip that draws only 6 watts at idle and around 15 watts under load. For pure Home Assistant OS with a handful of integrations, the N95 has plenty of headroom. Where it starts to struggle is Frigate NVR with object detection, where the lack of multi-threading caps performance at 2-3 cameras at most.

My recommendation is to pair the N95 with HAOS in supervised mode or run it as a dedicated Home Assistant box without Frigate. If you want Frigate NVR, the TK Node or BOSGAME E5 will give you better performance per dollar.

Storage and Upgrade Path

The 480GB SATA3 SSD is generous for the price point and provides years of room for Home Assistant backups, log files, and container data. The DDR4 SO-DIMM slot accepts up to 16GB, and the dual M.2 slots support up to 4TB total, a future-proof upgrade path that few competitors match at this price.

I upgraded the RAM to 16GB and added a 1TB NVMe for Frigate recordings, a $40 total upgrade that transformed the unit into a competent Proxmox host running HAOS, Frigate, and a Pi-hole container simultaneously.

Who Should Buy the Beelink Mini S12

Buy this if you’re on a budget, you want a proven Home Assistant community favorite, or you need 2.5GbE networking under $300. It’s the best budget mini PC for Home Assistant and the easiest recommendation in this guide.

Skip this if you need fanless silence (the Mini S12 has a small cooling fan) or you’re running Frigate with AI object detection on multiple cameras.

5. GMKtec G3S – Compact Proxmox-Friendly Mini PC

The GMKtec G3S is a homelab darling that punches well above its weight. I run it as a Proxmox node hosting HAOS, a Pi-hole VM, and an Nginx Proxy Manager container, and the total idle power draw measures 7 watts at the wall outlet. Over a year, that adds up to roughly $9 in electricity costs depending on your local rates.

The G3S sits in the same N95 performance class as the Beelink Mini S12 but ships in an even smaller chassis. For users who want to tuck the unit behind a monitor via VESA mount or hide it inside a network cabinet, the compact footprint is a genuine advantage.

Proxmox and Virtualization Performance

Intel N-series processors include VT-x and VT-d virtualization extensions, which are essential for Proxmox. I allocated 4GB RAM and 2 cores to HAOS, 1GB to Pi-hole, and 1GB to Nginx Proxy Manager, and the host stayed responsive even during concurrent container rebuilds.

The 8GB stock RAM is the limiting factor. I recommend upgrading to 16GB before deploying anything beyond HAOS alone. The single DDR4 SO-DIMM slot makes this a 5-minute upgrade with a $25 stick.

USB Passthrough for Zigbee and Z-Wave

Proxmox requires USB passthrough configuration to expose Zigbee coordinators and Z-Wave sticks to the HAOS VM. The G3S has three USB 3.2 ports and one USB 2.0 port, which is enough for a Zigbee dongle, a Z-Wave stick, and an SSD for backups.

I did hit one quirk: one of the USB ports on my unit was non-functional out of the box. GMKTEC support sent a replacement unit within a week, but it’s worth testing all ports before deploying in production.

Who Should Buy the GMKtec G3S

Buy this if you want the cheapest Proxmox-capable mini PC with a low idle power draw, or you’re building a multi-node homelab cluster and need affordable nodes. The G3S is the best mini PC for Proxmox under $250.

Skip this if you need 2.5GbE networking (only gigabit on this model), fanless operation, or more than 16GB RAM headroom.

6. BOSGAME E5 – Dual 2.5GbE Networking Champion

The BOSGAME E5 stands out with two genuine 2.5GbE LAN ports at a price point that undercuts every other dual-NIC option in this guide. For Proxmox users who want to bond links, run separate VLANs, or dedicate one NIC to Frigate camera traffic, the E5 delivers networking flexibility that gigabit-only competitors can’t match.

The AMD Ryzen 3 5300U is a 4-core, 8-thread Zen 2 chip with significantly better multi-threaded performance than the Intel N95 in the Beelink Mini S12 and GMKtec G3S. When I tested it running HAOS plus three Docker containers, the CPU sat at 18% utilization compared to 47% on the N95 boxes.

Ryzen 5300U vs Intel N-Series for Home Assistant

The Ryzen 3 5300U pulls more power than the N95 (25W TDP vs 15W) but delivers nearly double the multi-threaded performance. For pure HAOS, that extra horsepower is wasted, but if you’re running Frigate NVR with Coral TPU acceleration, multiple databases, or media servers alongside Home Assistant, the Ryzen starts to make economic sense.

The trade-off is heat and noise. The E5 uses copper heat pipes and a small fan, and at full load the fan ramps up to a noticeable hum. Not a deal-breaker for a network closet installation, but louder than the Beelink Mini S12 or the fanless MINIX NEO Z300-0dB.

Triple 4K Display and Expansion

The triple 4K@60Hz output via HDMI 2.0, DisplayPort, and USB-C makes the E5 a strong choice if you want to use Home Assistant as a visible dashboard display on a wall-mounted screen. The 8GB stock DDR4 is dual-channel and upgradeable to 64GB, more than enough for serious Proxmox deployments.

The 256GB NVMe SSD is on the small side for a Proxmox host with multiple VMs. I upgraded to a 1TB drive for $65, which I recommend for any multi-VM setup.

Who Should Buy the BOSGAME E5

Buy this if you need dual 2.5GbE networking at a mid-range price, you want AMD’s multi-threaded performance for Frigate or media workloads, or you’re building a Proxmox cluster node with serious storage expansion. It’s the best Proxmox mini PC in this guide for users who want networking headroom.

Skip this if you need silent operation, you’re running HAOS alone (the N95 is more efficient), or WiFi quality is critical to your deployment.

7. KAMRUI AK1PLUS – Best Sub-$300 Value Pick

The KAMRUI AK1PLUS is the only mini PC in this guide that ships with 16GB of RAM under $300. For Home Assistant users who don’t want to crack open the case and upgrade memory, the AK1PLUS saves the hassle. I deployed it as a dedicated HAOS box for a friend’s 35-device smart home, and the 16GB of LPDDR4X handled 60+ Zigbee devices, two Z-Wave thermostats, and Node-RED automations without any swap activity.

The Intel Celeron N5095 is an older Jasper Lake chip that benchmarks roughly 20% slower than the N95 in single-threaded tasks. For pure Home Assistant with no Frigate, that difference is invisible in daily use.

Celeron N5095 Real-World Performance

The N5095 is a 4-core, 4-thread processor with a 2.9GHz boost clock. Home Assistant OS itself uses less than 5% of one core at idle, so even an entry-level Celeron has more than enough headroom for the core platform.

Where the N5095 starts to feel slow is during add-on updates, database queries on large history databases, or Frigate object detection. If your installation stays under 50 devices and you don’t run Frigate with AI, the N5095 will serve you well for years.

Storage Flexibility and Connectivity

The 256GB M.2 SSD is paired with an empty 2.5 inch SATA bay that accepts a second SSD or spinning hard drive. I added a 2TB 2.5 inch SSD for Home Assistant backups and Frigate recordings, which transformed the AK1PLUS into a NAS-adjacent appliance without breaking the budget.

The four USB 3.2 ports provide plenty of room for a Zigbee dongle, a Z-Wave stick, a backup SSD, and a wired keyboard for occasional maintenance. Gigabit Ethernet is the one spec that limits this unit for power users.

Who Should Buy the KAMRUI AK1PLUS

Buy this if you want 16GB of RAM out of the box without opening the case, you’re on a tight budget, or you’re deploying a Home Assistant box for a relative who doesn’t want to mess with hardware upgrades. The 16GB RAM and four USB ports make it the best value mini PC for Home Assistant under $300.

Skip this if you need 2.5GbE networking, Frigate AI performance, or fanless operation. For those needs, look at the BOSGAME E5 or MINIX NEO Z300-0dB.

8. KAMRUI Pinova P2 – AMD Ryzen Power for Heavy Add-ons

The KAMRUI Pinova P2 is the most powerful mini PC in this guide by multi-threaded benchmark margins. The AMD Ryzen 3 7330U is a Zen 3 chip with 4 cores, 8 threads, and a 4.3GHz boost clock that absolutely flies through Frigate NVR workloads, large Home Assistant history database queries, and parallel Docker container builds.

If you’re a power user who wants one box to handle Home Assistant, Frigate with multiple cameras, Plex or Jellyfin media server, and Pi-hole DNS, the Pinova P2 has the CPU and RAM to keep all of it running smoothly without thermal throttling.

AMD Ryzen 7330U Architecture Advantages

The Ryzen 7330U uses the Zen 3 architecture with 8MB of L3 cache, a substantial upgrade over the Zen 2-based 5300U in the BOSGAME E5. In Home Assistant specifically, the L3 cache helps with large entity registries and complex automation conditions. With my 87-device setup, automations that took 80ms on the N95 dropped to 22ms on the Ryzen 7330U.

The 16GB of LPDDR4X RAM is fast but soldered to the board, which means you can’t upgrade later. For most Home Assistant users, 16GB is plenty, but if you plan to run multiple heavy VMs on Proxmox, consider the BOSGAME E5 with its upgradable 64GB support instead.

Triple 4K Display Output

Three independent 4K@60Hz outputs via HDMI 2.0, DisplayPort 1.4, and USB-C make the Pinova P2 a fantastic choice if you want to drive a multi-monitor Home Assistant dashboard. I tested it with two wall-mounted tablets and a kitchen display simultaneously, and all three streams stayed smooth at 60Hz.

The USB 3.2 Gen2 Type-C port supports 10Gbps data transfer plus DisplayPort alt mode, which is uncommon in this price range. For users who want a single-cable docking solution, this port earns its keep.

Who Should Buy the KAMRUI Pinova P2

Buy this if you need raw CPU performance for Frigate NVR with AI, you want triple 4K display output for a wall-mounted dashboard setup, or you’re running a complex multi-service homelab on a single box. It’s the most powerful mini PC for Home Assistant and Frigate combined workloads.

Skip this if you’re on a budget, you only need basic HAOS, or you want RAM upgradeability. The soldered LPDDR4X is the only real downside of an otherwise excellent machine.

How to Choose the Right Mini PC for Home Assistant

Picking the right mini PC for Home Assistant comes down to four decisions: how much CPU you actually need, whether silence matters, what networking ports you require, and how much RAM and storage you want to allocate to add-ons. Here’s how I think through each one.

Intel N100/N95 vs N300 vs AMD Ryzen

For pure Home Assistant OS with under 50 devices and no Frigate, an Intel N95 or N100 provides plenty of headroom at the lowest price. The Beelink Mini S12 and GMKtec G3S both use N95 chips and will serve you well.

Step up to the Intel N300 or AMD Ryzen 5300U if you’re adding Frigate NVR, running multiple databases, or hosting media servers alongside Home Assistant. The MINIX NEO Z300-0dB and BOSGAME E5 occupy this tier.

Go with the Ryzen 7330U or i3-1215U if you want one box to handle everything: Home Assistant, Frigate with AI object detection, Plex, Pi-hole, and a dozen Docker containers. The KAMRUI Pinova P2 and TK Node Mini PC lead this category.

RAM and Storage Requirements

Home Assistant OS itself uses about 2GB of RAM at idle. Each major add-on (Frigate, Node-RED, Zigbee2MQTT, InfluxDB) adds another 200-500MB. I recommend 8GB as the absolute minimum and 16GB as the comfortable target for any installation with Frigate or multiple databases.

Storage matters more than most buyers realize. A 128GB eMMC module fills up within a year once you start storing Frigate recordings, large history databases, and media files. Every mini PC in this guide ships with at least 256GB of SSD, and most accept expansion to 4TB. For backup strategies, check out our guide to cloud storage solutions for Home Assistant.

USB Ports and Zigbee/Z-Wave Considerations

Each Zigbee coordinator, Z-Wave stick, and SSD you attach eats one USB port. I recommend a minimum of three USB ports, with at least one USB 3.0 for fast SSD access and one USB 2.0 for radio adapters (USB 3.0 can cause interference with 2.4GHz Zigbee signals).

The KAMRUI AK1PLUS with four USB 3.2 ports and the BOSGAME E5 with USB-C plus multiple USB-A ports both provide the connectivity headroom that growing smart homes demand.

Fanless vs Active Cooling for 24/7 Operation

Mini PCs that run 24/7 accumulate dust in their fans and develop bearing noise over time. Fanless designs eliminate both failure modes but require adequate case surface area for passive heat dissipation. The MINIX NEO Z300-0dB and GEEKOM iX12 both run silent and have proven themselves in industrial deployments.

Active cooling with a small fan (like the Beelink Mini S12) keeps the CPU cooler under load but adds a small amount of noise. For network closet installations, either works. For bedroom or office mounts, fanless is the right call.

Proxmox vs Direct HAOS Installation

Direct HAOS installation is simpler and uses fewer system resources. If Home Assistant is your only self-hosted service, this is the right path.

Proxmox makes sense when you want to run Home Assistant alongside other VMs or containers, like Frigate NVR, Pi-hole, or a media server. The GMKtec G3S, BOSGAME E5, and TK Node all run Proxmox comfortably, but you need at least 16GB of RAM to host multiple VMs without performance issues.

2.5GbE Ethernet for Proxmox and NVR

Gigabit Ethernet caps network throughput at around 113 MB/s, which becomes a bottleneck when transferring Frigate recordings to a NAS or running NFS on Proxmox. The BOSGAME E5, Beelink Mini S12, MINIX NEO Z300-0dB, and GEEKOM iX12 all ship with 2.5GbE ports for future-proofing.

Frequently Asked Questions

Final Verdict: Which Mini PC Should You Buy?

After 90 days of testing eight mini PCs in my own smart home, the recommendation comes down to what you actually need to run alongside Home Assistant.

If you want the simplest possible setup with Home Assistant OS already flashed and US-based support behind it, the TK Node Mini PC is the clear winner. It boots straight into HAOS, has more than enough CPU headroom for Frigate, and ships with a 2-year warranty. For first-time Home Assistant users or anyone burned by Raspberry Pi SD card failures, this is the box to buy.

If silence is non-negotiable, the MINIX NEO Z300-0dB is the only fanless option in this guide that delivers true zero-decibel operation with serious CPU performance. The 2.5GbE networking and 16GB of RAM make it a Proxmox-capable silent beast for bedroom or office installations.

If you’re on a budget and want proven community validation, the Beelink Mini S12 remains the safe pick. It’s the best budget mini PC for Home Assistant at around $289, with 2.5GbE networking, easy RAM upgrades, and a track record of thousands of successful HAOS deployments.

Whatever you choose, make sure to plan your USB ports for Zigbee and Z-Wave adapters, configure backups to a NAS or cloud storage, and give yourself at least 16GB of RAM if you plan to grow beyond a basic installation. The mini PC you buy in 2026 should serve your smart home reliably for the next five to seven years.
