You don’t need a rack-mounted server to build a capable Proxmox homelab.
Modern Mini PCs can provide enough CPU performance for multiple virtual machines and containers while taking up very little space and using relatively little power.
The difficult part is choosing the right hardware.
For a Proxmox server, CPU performance is only part of the equation. RAM capacity, storage expansion, networking, cooling, power consumption, and PCIe connectivity can be just as important.
For most homelab users, a Mini PC with 32GB of RAM, a modern 6- or 8-core CPU, NVMe storage, and 2.5GbE networking is already a very capable starting point.
More demanding setups may benefit from 64GB or more RAM, multiple NVMe drives, 10GbE networking, or PCIe expansion.
In this guide, we’ll compare several Mini PCs based on what actually matters for a Proxmox host rather than simply ranking them by CPU performance.
If you want a specific, real-pricing reference point rather than a full lineup comparison, our $350 example Proxmox build walks through one concrete budget configuration in detail.

What Makes a Mini PC Good for Proxmox?
The fastest Mini PC isn’t necessarily the best Proxmox server.
A homelab has different requirements from a desktop PC. A machine that wins a short benchmark may not be the best choice if it consumes significantly more power, has poor cooling, provides only one network interface, or cannot be upgraded with enough RAM.
When choosing a Mini PC for Proxmox, we look at several important areas:
- CPU and virtualization support
- RAM capacity and upgradeability
- Storage options
- Networking
- Power consumption
- Cooling and sustained performance
- PCIe and expansion options
- Price and overall value
CPU and Virtualization
CPU performance determines how much work your virtual machines and containers can perform simultaneously.
For a small homelab, you don’t necessarily need a high-end processor.
A modern 6- or 8-core CPU can provide substantial headroom for workloads such as:
- Home Assistant
- Docker
- databases
- media servers
- Linux VMs
- development environments
- monitoring systems
Higher core counts become more useful when you start running CPU-intensive workloads or many virtual machines simultaneously.
This is why a 16-core processor such as the Ryzen 9 9955HX in the MINISFORUM MS-A2 belongs to a completely different class from a low-power processor such as the Intel N150.
The important question isn’t:
“Which Mini PC has the fastest CPU?”
It’s:
“How much CPU performance does my homelab actually need?”
RAM Is Often More Important Than CPU
One of the easiest mistakes when building a Proxmox server is spending most of the budget on CPU performance while running out of RAM.
As a practical starting point:
| RAM | Typical Use |
|---|---|
| 8GB | Very small experiments |
| 16GB | Beginner homelab |
| 32GB | Recommended starting point for many users |
| 64GB | Multiple VMs and heavier services |
| 96GB+ | Large or memory-heavy homelabs |
These are not Proxmox requirements. They are practical planning ranges.
Your memory budget isn’t only for the Proxmox host itself. Every VM and container consumes resources, and workloads such as databases, Windows VMs, and some media applications can quickly increase memory requirements.
That’s why RAM upgradeability matters.
A Mini PC with two SO-DIMM slots can be considerably more useful for a homelab than a system with soldered memory, even if both have similar CPU performance.
Storage: Two NVMe Slots Can Make a Big Difference
A single NVMe drive is enough to get started with Proxmox.
But two drives give you considerably more flexibility.
Depending on your configuration, additional storage can be useful for:
- VM storage
- container storage
- backups
- ZFS experiments
- separating workloads
- expanding the homelab later
The Beelink SER8 and GMKtec K8 Plus both provide two M.2 NVMe slots.
Higher-end systems such as the MINISFORUM MS-A2 provide substantially more storage and expansion options.
For a simple homelab, you probably don’t need several drives.
For a virtualization-heavy or storage-focused server, however, additional storage connectivity can become a major advantage.
Networking Matters More in a Homelab
A Mini PC with 1GbE can run Proxmox perfectly well.
But 2.5GbE is an attractive middle ground for modern homelabs, particularly if your Proxmox server communicates frequently with a NAS or other systems on the network.
Multiple Ethernet ports can also be useful for:
- network segmentation
- routing experiments
- dedicated management networks
- virtualized firewalls
- lab networking
- connecting separate networks
This is one of the biggest advantages of the GMKtec K8 Plus.
It provides two 2.5GbE Ethernet ports, giving it considerably more networking flexibility than a typical Mini PC with a single Ethernet interface.
The MINISFORUM MS-A2 goes much further with 10GbE networking and multiple Ethernet interfaces.
For a beginner, this may be unnecessary.
For an advanced homelab, it can be extremely useful.
Power Consumption Matters When Your Server Runs 24/7
A Proxmox host is often running all day, every day.
That makes idle power consumption more important than it would be for a normal desktop PC.
For example:
10W × 24 hours × 365 days ÷ 1000
= 87.6 kWh/year
At 20W:
20W × 24 hours × 365 days ÷ 1000
= 175.2 kWh/year
The actual cost depends on your electricity rate.
This is why measured power consumption is more useful than simply comparing CPU TDP figures.
TDP is not the same thing as the electricity consumed by the complete Mini PC.
For a server that runs 24/7, even a relatively small difference in idle consumption can add up over several years.
Cooling and Sustained Performance
A Proxmox host can spend hours under sustained workloads.
That’s different from running a short benchmark.
A good Mini PC needs to maintain reasonable temperatures and performance without excessive fan noise or thermal throttling.
Cooling design is therefore an important part of our evaluation.
The Beelink SER8, for example, uses a vapor-chamber-based cooling system.
The GMKtec K8 Plus uses a dual-fan cooling design.
Higher-performance systems such as the MINISFORUM MS-A2 require more substantial cooling because of their significantly higher CPU performance.
For a homelab, sustained performance and reasonable noise levels are often more important than winning a short benchmark.
IOMMU and PCI Passthrough
Advanced Proxmox users may want to pass physical hardware directly to a virtual machine.
Common examples include:
- GPUs
- network controllers
- storage controllers
- USB controllers
- other PCIe devices
This is where IOMMU becomes important.
A simplified configuration might look like:
Proxmox
|
+-- VM
|
+-- PCIe device
|
+-- GPU
+-- NIC
+-- Controller
However, Mini PCs can differ significantly in how their hardware is exposed to the operating system.
IOMMU grouping, BIOS options, PCIe connectivity, and device compatibility can all affect whether a particular passthrough configuration works as expected.
For this reason, we don’t treat PCI passthrough as a guaranteed feature simply because a Mini PC has a particular connector.
Best Mini PCs for Proxmox
Beelink SER8
Best Overall
The Beelink SER8 is our pick for the best overall Proxmox Mini PC because it provides a strong balance between CPU performance, storage expansion, cooling, memory capacity, and power efficiency.
Its Ryzen 7 8845HS provides 8 cores and 16 threads, giving it plenty of CPU headroom for a typical homelab.
Key Specifications
- AMD Ryzen 7 8845HS
- 8 cores / 16 threads
- Radeon 780M integrated graphics
- 2 × DDR5 SO-DIMM
- 2 × M.2 PCIe 4.0
- 2.5GbE Ethernet
- USB4 connectivity
- Vapor chamber cooling
Why We Like It
The SER8 doesn’t try to solve every possible homelab problem.
Instead, it provides a balanced hardware platform that works well for the majority of users.
The 8-core CPU is powerful enough for a substantial collection of VMs and containers, while the two NVMe slots provide room for storage expansion.
The cooling system is another important advantage for a machine that may spend most of its life running continuously.
Pros
- Strong 8-core / 16-thread CPU
- Two NVMe slots
- Two RAM slots
- Modern integrated graphics
- 2.5GbE networking
- Good cooling design
- Suitable for a 24/7 homelab
Cons
- Only one Ethernet port

- High-end RAM configurations may not make financial sense
Best For
The SER8 makes the most sense for users who want:
- a general-purpose Proxmox server
- several VMs and containers
- a relatively quiet homelab
- good storage expansion
- a compact 24/7 server
Don’t Buy It If…
You specifically need multiple physical Ethernet ports, OCuLink expansion, or high-speed 10GbE networking.
In that case, the K8 Plus or MS-A2 may be a better fit.
GMKtec K8 Plus
Best Homelab Value
The GMKtec K8 Plus is particularly interesting for homelab users because its value isn’t just its CPU.
Like the SER8, it uses AMD’s Ryzen 7 8845HS with 8 cores and 16 threads.
But the K8 Plus adds several features that are particularly useful in a homelab:
- two 2.5GbE Ethernet ports
- OCuLink
- two USB4 ports
- two M.2 NVMe slots
- two DDR5 SO-DIMM slots
Why We Like It
For a normal desktop computer, two Ethernet ports and OCuLink may be unnecessary.
For a homelab, they can be much more useful.
Two physical Ethernet interfaces provide additional options for network experiments, segmentation, routing, and virtualized networking.
OCuLink also provides a path toward external PCIe expansion.
That makes the K8 Plus more interesting to users who want to experiment with hardware beyond the Mini PC itself.
Pros
- Ryzen 7 8845HS
- Two 2.5GbE ports
- OCuLink
- Two USB4 ports
- Two NVMe slots
- Two RAM slots
- Strong homelab-oriented feature set
Cons
- Expansion is still more limited than a conventional desktop
- Cooling and noise should be considered under sustained load
- Maximum RAM depends on the configuration and modules used
- May be unnecessary for a basic Proxmox installation
Best For
The K8 Plus is a particularly good fit for users who want:
- multiple Ethernet ports
- network experimentation
- OCuLink expansion
- multiple NVMe drives
- a powerful but compact homelab node
Don’t Buy It If…
You don’t need the additional networking or expansion features.
If you simply want a quiet and powerful Proxmox host, the SER8 may be the simpler choice.
MINISFORUM MS-A2
Best High-End Proxmox Mini PC
The MINISFORUM MS-A2 is less like a traditional Mini PC and more like a compact server.
Its Ryzen 9 9955HX provides 16 cores and 32 threads, giving it substantially more CPU headroom than the SER8 or K8 Plus.
But CPU performance is only one reason to consider it.
The MS-A2 also focuses heavily on networking and storage expansion.
Key Specifications
- AMD Ryzen 9 9955HX
- 16 cores / 32 threads
- Up to 96GB DDR5 memory
- Multiple NVMe/U.2 storage options
- 10GbE networking
- Additional 2.5GbE networking
- PCIe expansion
Why We Like It
The MS-A2 makes sense when a typical Mini PC starts running into its limits.
For example, an advanced homelab might include:
- several Linux VMs
- Windows VMs
- databases
- media services
- NAS workloads
- 10GbE networking
- multiple containers
- development environments
In that scenario, additional CPU cores, memory capacity, storage connectivity, and networking can all become useful.
Pros
- 16 cores / 32 threads
- High CPU performance
- 10GbE networking
- Multiple network interfaces
- Multiple storage options
- PCIe expansion
- Suitable for demanding virtualization workloads
Cons
- Expensive
- More power-hungry than low-power Mini PCs
- Overkill for a basic homelab
- More complex than most beginners need
Best For
The MS-A2 is best suited to advanced users building a dense virtualization, networking, or storage-focused homelab.
Don’t Buy It If…
You’re only planning to run Home Assistant, Pi-hole, a few containers, and one or two lightweight VMs.
You can spend much less and still have plenty of performance.
Beelink EQ14
Best Budget Option
The Beelink EQ14 takes a completely different approach.
Instead of maximizing CPU performance, it focuses on low power consumption and affordability.
Its Intel N150 is a 4-core processor designed for low-power systems rather than heavy virtualization workloads.
That doesn’t make it a bad Proxmox machine.
It simply means that it should be used for the right workloads.
Good For
- Home Assistant
- Pi-hole
- Docker
- lightweight Linux VMs
- LXC containers
- monitoring
- learning Proxmox
Not Ideal For
- many CPU-intensive VMs
- multiple Windows VMs
- heavy databases
- CPU-intensive media workloads
- large virtualization clusters
Best For
The EQ14 makes the most sense if your main goal is to learn Proxmox and build a small home server without spending several hundred dollars on hardware.
Used Lenovo ThinkCentre, HP EliteDesk, and Dell OptiPlex Tiny PCs
Best Used Option
Before buying a new budget Mini PC, don’t overlook the used business-PC market.
Systems such as:
- Lenovo ThinkCentre Tiny
- HP EliteDesk Mini
- Dell OptiPlex Micro
can offer excellent value on the used market.
These machines were originally designed for business environments, so many models offer good Linux compatibility, accessible components, and mature hardware platforms.
However, the exact model matters.
A newer generation with a more efficient CPU can be a much better Proxmox host than an older model that happens to be cheaper.
When shopping used, check:
- exact CPU generation
- RAM slots
- maximum RAM
- NVMe support
- SATA support
- Ethernet controller
- power adapter
- condition
- warranty
- availability of replacement parts
Don’t simply buy the cheapest Tiny PC you can find.
Which Mini PC Should You Buy?
The easiest way to choose is to start with your workload rather than the hardware specifications.
You want the best all-around option
Buy the Beelink SER8.
It offers a strong combination of CPU performance, storage expansion, cooling, and memory upgradeability.
You need multiple Ethernet ports
Look at the GMKtec K8 Plus.
Its dual 2.5GbE configuration makes it particularly interesting for homelab networking.
You need serious CPU and networking performance
Look at the MINISFORUM MS-A2.
It’s expensive, but its 16-core CPU, 10GbE networking, storage options, and expansion capabilities make it much more suitable for demanding workloads.
You want the cheapest reasonable way into Proxmox
Consider the Beelink EQ14 or a used business Mini PC.
You don’t need a high-end CPU to learn Proxmox.
You have a very limited budget
Check the used market first.
A well-chosen used ThinkCentre Tiny, EliteDesk Mini, or OptiPlex Micro can offer excellent value.
How Much RAM Do You Need for Proxmox?
For many users, 32GB is a good starting point.
16GB can work for a small lab, particularly when you’re running mostly lightweight containers.
64GB becomes attractive when you start running several VMs or memory-heavy services.
If you already know that you’re going to run many VMs, buy as much RAM as your workload requires rather than upgrading later.
Remember that RAM is often harder to work around than CPU performance.
You can reduce CPU allocation to a VM.
Running out of RAM is a much more fundamental limitation.
How Many VMs Can a Mini PC Run?
There is no universal number.
A Mini PC could run a handful of lightweight VMs or many more small containers, depending on how much CPU, RAM, and storage each workload requires.
For example:
Small Homelab
Home Assistant
Pi-hole
Docker
Ubuntu VM
Monitoring
A modest Mini PC can handle this easily.
Medium Homelab
Home Assistant
Jellyfin
Docker
Ubuntu VM
Windows VM
Database
Monitoring
Now CPU, RAM, and storage become much more important.
Heavy Homelab
Multiple Windows VMs
NAS
Database
Media server
Development environments
GPU workload
Multiple services
At this point, a high-end Mini PC such as the MS-A2 starts making more sense.
The important thing is not the number of VMs.
It’s the resource requirements of those VMs.
Mini PC vs. Used Server for Proxmox
Mini PCs aren’t automatically better than traditional servers.
They simply optimize for a different type of homelab.
| Mini PC | Used Server | |
|---|---|---|
| Size | Excellent | Poor |
| Power consumption | Usually lower | Usually higher |
| Noise | Usually lower | Often higher |
| RAM capacity | Limited | Usually much higher |
| Drive capacity | Limited | Much higher |
| PCIe expansion | Limited | Excellent |
| Cost | Low to moderate | Can be very low used |
| Living-room friendly | Yes | Usually no |
A Mini PC is usually a better choice when you care about:
- low power consumption
- small size
- low noise
- simple deployment
A used server can be better when you need:
- lots of drives
- ECC memory
- large RAM capacity
- multiple PCIe cards
- enterprise networking
- large storage arrays
For many home users, a Mini PC is the more practical starting point.
Can You Build a Proxmox Cluster With Mini PCs?
Absolutely.
One Mini PC can be a useful Proxmox host.
Multiple Mini PCs can become a much more interesting homelab.
For example:
Proxmox Cluster
|
+-----------+-----------+
| | |
Node 1 Node 2 Node 3
| | |
VMs VMs VMs
LXC LXC LXC
Three similar Mini PCs can provide a much better environment for learning:
- clustering
- migration
- replication
- high availability concepts
- distributed storage
- network design
However, a cluster also introduces additional networking and storage considerations.
If you’re building a cluster, don’t simply buy three of the cheapest Mini PCs you can find.
Network connectivity, RAM capacity, storage reliability, and hardware consistency become much more important.
Final Verdict
The best Mini PC for Proxmox depends on what you want your homelab to do.
For most users, the Beelink SER8 is the strongest all-around choice because it combines a powerful 8-core CPU with good storage expansion, modern connectivity, and a compact form factor.
The GMKtec K8 Plus is more interesting if your homelab needs multiple network interfaces or OCuLink expansion.
The MINISFORUM MS-A2 is the choice for users who need substantially more CPU performance, high-speed networking, and storage expansion.
The Beelink EQ14 is a sensible entry point for lightweight workloads and learning Proxmox.
And if your budget is extremely limited, don’t ignore the used business-PC market.
Ultimately, the best Proxmox Mini PC isn’t necessarily the fastest one.
It’s the machine that gives you enough CPU and RAM for your workloads while providing the storage, networking, expansion, cooling, and power efficiency your homelab actually needs.
