Best Mini PC for Proxmox in 2026 (By Budget and Use)

If you’re building a Proxmox home lab, you don’t necessarily need a large server.

A modern Mini PC can give you a surprisingly capable Proxmox host in a small, quiet package. The difficult part is choosing one that makes sense for virtualization, rather than simply choosing the Mini PC with the fastest benchmark score.

For Proxmox, we care about:

• CPU virtualization support
• RAM capacity and upgradeability
• NVMe storage
• Ethernet connectivity
• PCIe/IOMMU capabilities
• cooling under sustained workloads
• power consumption
• expansion options
• price

In this guide, we’ll focus on the GMKtec K8 Plus and Beelink SER8, two Mini PCs that make particularly interesting Proxmox home-lab hosts.

What Makes a Mini PC Good for Proxmox?

A Mini PC that is excellent for Windows gaming or office work isn’t automatically an excellent Proxmox server.

Proxmox VE requires a 64-bit Intel or AMD CPU with the appropriate virtualization support. Fast storage is recommended, and additional network interfaces can be useful for more advanced configurations.

For PCIe passthrough, the platform also needs the appropriate IOMMU/VT-d/AMD-d capabilities.

That gives us a useful checklist.

CPU virtualization

Modern AMD Ryzen processors support AMD-V virtualization.

For a home lab, the important question isn’t simply:

How fast is the CPU?

Instead ask:

What workloads am I going to run simultaneously?

A host running a few lightweight Linux containers has very different requirements from one running several VMs, a NAS, Home Assistant, databases and a Windows VM.

RAM

RAM is often more important than CPU once you start running multiple VMs.

Remember that Proxmox itself needs memory, and every VM or container consumes additional resources.

These are practical planning guidelines, not hard Proxmox limits.

If you’re buying a Mini PC specifically for Proxmox, upgradeability matters. Two SO-DIMM slots are much more useful than permanently soldered memory.

NVMe storage

Proxmox recommends fast storage, and SSDs are generally preferable for VM workloads.

Two NVMe slots are useful because they give you more options as the lab grows.

For example:

• one drive for the Proxmox installation and general storage
• another drive for VM/container storage
• separate storage later for backups or another storage strategy

The exact layout depends on how you intend to use ZFS, local storage, NAS storage or backups.

Two drives do not automatically mean redundancy, and neither is a substitute for backups.

Ethernet

A single 1GbE interface can be perfectly adequate for a simple lab.

Multiple NICs become useful when you’re experimenting with:

• OPNsense/pfSense
• VLANs
• network segmentation
• router/firewall VMs
• separate management networks
• storage traffic
• Proxmox clusters

This is one reason the K8 Plus is particularly interesting.

GMKtec K8 Plus for Proxmox

The GMKtec K8 Plus is one of the more interesting Mini PCs for a Proxmox home lab because its hardware goes beyond the usual “fast CPU in a tiny box” formula.

GMKtec lists:

• AMD Ryzen 7 8845HS
• 8 cores / 16 threads
• Radeon 780M graphics
• 2 × DDR5-5600 SO-DIMM slots
• up to 128 GB RAM (current manufacturer specification reviewed September 19, 2026)
• 2 × M.2 2280 PCIe 4.0 NVMe slots
• dual 2.5GbE Intel I226V Ethernet
• 2 × USB4
• OCuLink PCIe Gen4 ×4
• Wi-Fi 6E

Source: GMKtec K8 Plus official specifications

Why the K8 Plus is interesting for Proxmox

Dual 2.5GbE

This is probably the biggest reason to consider the K8 Plus for a homelab.

Two Ethernet ports make it easier to experiment with network topology without immediately adding a USB NIC or PCIe expansion.

For example, the Mini PC could potentially be used as a host for a firewall/router VM while maintaining separate physical network connections.

That doesn’t mean you should automatically turn every K8 Plus into a router. It simply gives you more flexibility.

Two NVMe slots

Two M.2 PCIe 4.0 slots are useful for a growing virtualization host.

You can start with one SSD and add another later instead of replacing the original drive.

OCuLink

The K8 Plus also includes an OCuLink PCIe Gen4 ×4 connection.

This opens up additional expansion possibilities for advanced homelab projects.

One important limitation from GMKtec is that OCuLink is not hot-pluggable. Power the machine off before connecting or disconnecting an OCuLink device.

RAM

GMKtec currently lists two SO-DIMM slots and support for up to 128 GB of DDR5-5600 memory. Published limits and retailer listings have differed over time, so verify the exact unit, current firmware support, and validated module configuration before buying a high-capacity kit.

That gives the K8 Plus a useful upgrade path for virtualization.

K8 Plus limitations

The K8 Plus isn’t perfect.

Consider:

• OCuLink is not hot-pluggable.
• Mini PC cooling still has physical limits compared with a large server.
• A Mini PC is not automatically a good choice for redundant storage.
• Consumer hardware does not provide the same enterprise management features as a dedicated server.
• Manufacturer specifications are not the same thing as independent long-term reliability testing.

For a home lab, these tradeoffs are often acceptable.

Beelink SER8 for Proxmox

The Beelink SER8 is another strong candidate for a compact Proxmox host.

Its Ryzen 7 8845HS configuration includes:

• AMD Ryzen 7 8845HS
• 8 cores / 16 threads
• Radeon 780M
• dual SO-DIMM DDR5-5600 memory
• dual M.2 PCIe 4.0 SSD slots
• 2.5GbE networking
• Wi-Fi 6
• USB4
• vapor-chamber-based cooling system

Source: Beelink SER8 official specifications

Why the SER8 is interesting for Proxmox

The SER8 is attractive if you want a straightforward Mini PC with strong CPU performance, two NVMe slots and 2.5GbE networking.

Its cooling design is another differentiator.

Beelink advertises a vapor-chamber cooling system and a 32 dB operating figure. Treat the noise figure as a manufacturer claim rather than an independent measurement.

Dual NVMe

Two PCIe 4.0 M.2 slots provide plenty of flexibility for a compact home lab.

2.5GbE

A 2.5GbE interface is a useful step up from traditional 1GbE networking, particularly when moving large files to and from the host.

Quiet operation

If the server is going to live in a bedroom, office or living area, noise can matter as much as raw performance.

The SER8 is designed around that use case.

SER8 limitations

The SER8’s main disadvantage compared with the K8 Plus for our particular use case is networking/expansion.

If your goal is:

• multiple physical networks
• router/firewall experimentation
• more flexible network topology
• external PCIe expansion

the K8 Plus has a stronger feature set.

If your goal is simply:

I want a powerful, compact and relatively quiet Proxmox server.

the SER8 is easier to recommend.

K8 Plus vs SER8 for Proxmox

Both machines use the Ryzen 7 8845HS platform in the configurations we’re comparing, so the decision isn’t primarily about CPU.

It’s about everything around the CPU.

Which one should you buy?

Choose the K8 Plus if:

• you want two physical Ethernet ports
• you’re interested in OCuLink expansion
• you’re building a more experimental homelab
• you want more networking flexibility
• you plan to experiment with firewall/router VMs

Choose the SER8 if:

• you want a simple single-node Proxmox host
• noise is important
• you want two NVMe slots
• you don’t need dual Ethernet
• you prefer Beelink’s cooling design

Our pick

For a Proxmox-focused homelab, we’d give the K8 Plus the edge because its dual 2.5GbE ports and OCuLink connection provide more expansion options.

For a simple and quiet single-node lab, the SER8 is arguably the cleaner choice.

The final decision should also consider the current price. Don’t pay a large premium for features you won’t use.

Budget N150 mini PCs for Proxmox

An Intel N150 box is a good Proxmox host only if you are honest about the workload.

Good fit:

• always-on node for LXCs (Pi-hole, AdGuard, Home Assistant, Navidrome)
• one or two light Linux VMs
• a decode box if you care about Quick Sync

Bad fit:

• several Windows VMs
• a busy Minecraft + database + media stack on one box
• anything that wants 64 GB of RAM

Typical N150 kits top out well below the K8 Plus / SER8. Treat them as a quiet appliance node, not as “the” homelab server.

10GbE and cluster-class mini PCs

If the query in your head is “best mini PC for virtualization” rather than “quiet box for four containers,” look at the MS-01 / MS-A2 class:

• dual 10GbE (often SFP+)
• extra 2.5GbE
• a real PCIe slot for an HBA or low-profile GPU
• higher memory ceilings

That is a different machine than a K8 Plus. You pay in watts, fans, and price. For a learning cluster it can still beat a pile of used 1GbE tinies, because the network is no longer the joke part of the build.

Do not buy 10GbE “for Proxmox” if every client on the LAN is 1GbE and you have no NAS that can fill the pipe.

Mini PC für Proxmox

Die Kriterien sind dieselben: zwei RAM-Slots, möglichst zwei NVMe, und ein zweiter NIC nur wenn du Firewall/VLANs wirklich nutzen willst. K8 Plus, wenn du zwei 2.5GbE und OCuLink willst. SER8, wenn es leise sein soll. N150, wenn der Rechner 24/7 läuft und wenig tun muss.

How Much RAM Do You Need for Proxmox?

There is no universal answer.

Proxmox itself requires only a portion of the host’s memory. The rest is available for your VMs and containers.

Proxmox’s documentation notes that additional memory is needed for guests and that ZFS/Ceph workloads require additional memory.

Source: Proxmox VE hardware requirements

For a new home lab, I’d use:

16 GB

Fine for experimenting with containers and a small number of lightweight VMs.

32 GB

A very good starting point for a general-purpose Proxmox home lab.

64 GB

Where things become considerably more comfortable if you plan to run multiple VMs.

96 GB+

Useful for larger experiments and heavier workloads, assuming the specific Mini PC supports it.

Don’t buy more RAM simply because the machine supports it. Buy according to the workloads you actually intend to run.

How Many VMs Can a Mini PC Run?

This question is difficult to answer with a single number.

A VM running a small Linux service may use very little CPU and RAM.

A Windows VM, database server, Kubernetes cluster or media-processing workload can consume considerably more.

For example:

Lab A

• 3 Linux containers
• Home Assistant
• Pi-hole
• small web server

Lab B

• Windows VM
• OPNsense
• Kubernetes
• database
• media server
• multiple Linux VMs
• several development environments

Both are “a Proxmox home lab,” but their resource requirements are nowhere near identical.

Think about RAM and storage first, then CPU.

Do You Need Dual Ethernet for Proxmox?

No.

A single NIC is enough for a simple Proxmox installation.

Two or more physical NICs become useful when you’re experimenting with:

• firewall/router VMs
• VLANs
• network segmentation
• separate management networks
• storage networks
• clusters

This is why dual 2.5GbE is a meaningful advantage of the K8 Plus.

Proxmox lists additional/redundant NICs as useful depending on the preferred storage technology and cluster configuration.

Mini PC vs Used Dell or Lenovo Tiny

A Mini PC isn’t automatically the best value.

If you are still choosing between a mini PC, an existing machine, and a used business PC, start with the home server build planner for a workload-based route.

Used business machines can be excellent homelab hardware.

A used Dell OptiPlex Micro, Lenovo Tiny or HP Mini can offer:

• cheap replacement parts
• mature Linux support
• good availability
• low purchase price
• business-class construction

Modern Mini PCs can offer:

• much newer CPUs
• better integrated graphics
• 2.5GbE
• multiple NVMe slots
• USB4
• lower physical footprint
• newer wireless connectivity

If your goal is the cheapest possible Proxmox cluster, used business PCs deserve serious consideration.

If you want a modern compact machine with strong CPU performance and current connectivity, a new Mini PC can make more sense.

Used tinies can make sense when you want three nodes for quorum and accept 1GbE and older CPUs. New mini PCs can make more sense when you need features such as 2.5GbE or two NVMe slots. Future performance depends on the workloads you add; a model year is not a guarantee that a CPU will remain sufficient.

One possible hybrid design is a modern mini PC for heavier workloads plus cheaper used systems for lightweight cluster or backup roles. Whether that is sensible depends on quorum design, storage, power use, and whether the extra nodes solve a real requirement.

Is the K8 Plus Good for a Proxmox Cluster?

Potentially, yes, but the answer depends on what you mean by “cluster.”

A few Mini PCs can be an excellent learning platform for Proxmox clustering.

However, a serious production cluster introduces additional requirements around:

• networking
• storage
• quorum
• redundancy
• backups
• failure handling

Don’t confuse:

I built a three-node Proxmox lab

with:

I built a highly available production cluster.

For learning, Mini PCs can be fantastic.

For production, evaluate the entire system rather than just the CPU.

Should You Use ZFS on a Mini PC?

You can, but storage and memory planning matter.

Proxmox documents additional memory requirements for ZFS and Ceph.

If you are building a simple lab, you don’t need to choose ZFS simply because it is available.

Choose your storage architecture based on what you’re trying to learn or operate.

If your primary goal is:

Run a few VMs and containers.

keep the storage setup simple.

If your goal is:

Learn ZFS, snapshots, replication and storage management.

then the additional complexity can be worthwhile.

Frequently Asked Questions

Can I run Proxmox on a Mini PC?

Yes. Proxmox VE supports 64-bit Intel and AMD systems with the required virtualization capabilities. Modern Mini PCs can be very capable Proxmox hosts.

Is 16 GB RAM enough for Proxmox?

It can be enough for a small lab, especially when running lightweight containers and a small number of VMs. 32 GB is a more comfortable starting point for many home labs.

Is 32 GB enough for a Proxmox home lab?

For many users, yes. The actual requirement depends on the number and type of VMs and containers.

Is 64 GB better?

If you’re planning multiple VMs, development environments or heavier services, 64 GB gives you substantially more headroom.

Is dual Ethernet necessary?

No. It is useful rather than mandatory.

Is the K8 Plus better than the SER8?

For networking and expansion, we prefer the K8 Plus. For a simpler, quiet single-node setup, the SER8 is a strong alternative.

Can I use PCIe passthrough?

Potentially. Proxmox requires the appropriate CPU/platform virtualization features for PCIe passthrough. The exact passthrough behavior depends on the hardware, firmware and device.

Do not assume that every PCIe device will work perfectly just because the CPU supports AMD-V/IOMMU.

What is the best mini PC for Proxmox in 2026?

For most new labs: K8 Plus if you want dual 2.5GbE and expansion, SER8 if you want quiet and simple. N150 if the box must sip power. MS-01/MS-A2 class if you need 10GbE or a PCIe slot.

Is a mini PC good enough for virtualization?

Yes, if RAM and storage match the guests. Virtualization on these boxes is limited by memory and I/O first, not by whether the badge says “server.”

Can I start with 16 GB and upgrade later?

Only if the machine has two SO-DIMM slots and you are not buying a soldered N150 kit. Soldered memory is how a cheap box becomes a dead end.

Can a Mini PC replace a server?

For a home lab, often yes.

For production workloads where redundancy, remote management, ECC memory, replaceable components and enterprise support are important, a dedicated server may still be the better choice.

Final Verdict

If you want to build a Proxmox home lab without buying a large server, a modern Mini PC can be an excellent starting point.

2. Do I need one or two Ethernet ports?
3. How many NVMe drives do I want?
4. Will I use PCIe passthrough?
5. Do I need external expansion?
6. How important is noise?
7. What is the current price?

The best Proxmox Mini PC is the one that fits the lab you actually intend to build.
