Best Mini PCs for Proxmox VE in 2026

Why Mini PCs Make Great Proxmox Hosts

Mini PCs have become the go-to hardware for Proxmox homelabs and small business deployments. They draw a fraction of the power of traditional servers, run near-silent, and take up almost no space. With the right model, you get enough compute for 10-20 lightweight VMs and containers, full virtualization support (VT-x/VT-d), and even multiple NICs for proper network segmentation.

Since Intel discontinued the NUC line in 2023, a wave of alternatives from ASUS, Beelink, MinisForum, and others have filled the gap — often with better specifications at lower prices. Here is what to look for and which models deliver the best value for Proxmox in 2026.

Key Features to Look For

Not every mini PC works well as a Proxmox host. Prioritize these features:

• VT-x and VT-d support: Required for KVM virtualization and PCI passthrough. Virtually all modern x86 mini PCs support this, but verify in the BIOS — some ship with VT-d disabled.
• Upgradeable RAM: Avoid models with soldered memory. You want at least two SO-DIMM slots for 32-64 GB capacity.
• NVMe slot + optional SATA: One NVMe for the OS and VMs, plus a second slot or 2.5" bay for additional storage.
• Multiple NICs: Dual 2.5 GbE is ideal. Single-NIC models work but require VLAN trunking for network separation.
• Low idle power: 6-15W at idle means you can run the system 24/7 without a noticeable electricity bill impact.

Intel N100/N305: Budget Powerhouses

The Intel Alder Lake-N series has become the default recommendation for budget Proxmox builds. The N100 (4 cores, 6W TDP) and N305 (8 cores, 15W TDP) punch well above their price point:

• Beelink EQ12 Pro / EQ13 (N305): Dual 2.5 GbE Intel i226-V NICs, up to 32 GB DDR5, one NVMe slot. Around $200-250 barebones. Excellent for a single-node homelab.
• MinisForum UN305 / UN100: Similar specs, sometimes with USB-C display output. Check for the Intel i226-V NIC specifically — some models use Realtek NICs that have poorer driver support in Proxmox.
• Topton N100/N305 boards: Bare motherboards with 4x 2.5 GbE i226-V ports, designed to be used as routers but excellent as compact Proxmox nodes. Available on AliExpress for under $150. You supply your own case, RAM, and storage.

Limitations: N100/N305 CPUs do not support ECC memory and have limited PCIe lanes (no x16 slot for GPU passthrough). They also top out at 16 GB RAM officially, though many boards support 32 GB with the right DDR5 modules.

AMD Ryzen: The Performance Tier

When you need more cores, more RAM, and unofficial ECC support, AMD Ryzen mini PCs are the next step up:

• MinisForum UM780 XTX / UM790 Pro (Ryzen 7 7840HS): 8 cores / 16 threads, up to 64 GB DDR5, dual NVMe slots, USB4. Integrated Radeon 780M GPU for hardware transcoding. Idles around 10-12W. Around $400-500 barebones.
• ASUS NUC 14 Pro (Ryzen 7 8845HS): ASUS's successor to the Intel NUC line. Thunderbolt 4, dual NVMe, up to 64 GB. Premium build quality. Around $500-600.
• Beelink SER7 / SER8 (Ryzen 7 8845HS): Competitive pricing with dual 2.5 GbE, OCuLink port on some models for external GPU. Good all-around choice.

Ryzen mini PCs can comfortably handle 15-25 VMs and containers, run Plex transcoding in the background, and support PCI passthrough for the integrated GPU if you add a discrete NIC via USB or M.2 adapter.

Multi-NIC Options for Network Segmentation

Running Proxmox with a single NIC works, but dedicated NICs for management, VM traffic, and storage make your setup more robust and easier to troubleshoot. Here are your options:

• Built-in dual NIC: Models with dual Intel i226-V are the simplest path. One NIC for Proxmox management, one for VM traffic (with VLANs if needed).
• USB 3.0 Ethernet adapters: Add a 2.5 GbE NIC via USB for around $15. Works well for management traffic but avoid for storage replication.
• M.2 to NIC adapters: Some mini PCs have an unused M.2 E-key or A-key slot. M.2 to Intel i225/i226 adapters give you a third native NIC.
• Topton quad-NIC boards: Purpose-built for networking with four 2.5 GbE ports. Ideal if you want to run OPNsense in a VM alongside other workloads.

Power Consumption Comparison

The energy savings alone can justify choosing mini PCs over used enterprise servers, especially if you are running hardware 24/7.

Building a Mini PC Cluster

Three mini PCs make an excellent Proxmox cluster with high availability. A popular budget cluster build:

• 3x Beelink EQ13 (N305) — each with 32 GB DDR5 and a 500 GB NVMe
• 1x managed switch with VLAN support (e.g., TP-Link TL-SG108E)
• Shared storage: Either a small NAS with NFS/iSCSI, or Ceph across the three nodes (though N305 CPUs may struggle with heavy Ceph workloads)
• Total cost: Under $900 for the cluster, plus the switch and storage

This gives you live migration, HA failover, and enough resources for a dozen containers and several VMs. For managing a cluster of mini PCs, ProxmoxR provides a streamlined way to monitor all your nodes and VMs from one interface — particularly useful when you have multiple small nodes rather than one large server.
