Whether you are running a heavy-duty Plex server or a full virtual lab, the cooling solution keeps the i9 chip from throttling during long compile times. However, the fan noise can get quite high when all cores are pegged. If you are looking for a silent machine for a bedroom setup, you should skip this and look at a lower-wattage unit.
- Unrivaled connectivity with two 10GbE ports
- Actual PCIe expansion allows for custom hardware
- Supports up to 96GB of DDR5 RAM
- Cooling fans can become audibly distracting under heavy load
- Higher price point than standard consumer mini PCs
Beelink SER8 View on Amazon

The Beelink SER8 offers incredible performance-per-dollar, especially for those who need a balance of CPU power and efficiency. The Ryzen 8845HS is an absolute beast for multitasking, and I found it handled a large Docker stack with ease while remaining surprisingly quiet. The all-metal build feels premium, and the internal design is clean, which makes adding extra NVMe storage a breeze. Compared to the more expensive MS-01, you do lose the 10GbE networking and the PCIe slot, but for 90% of home lab users running home automation, Nginx proxies, or a media server, this machine is more than capable. It’s perfect if you don’t need niche enterprise networking. If you are a network engineer planning to run a virtualized firewall cluster, you might find the lack of dual NICs a dealbreaker.
- Excellent thermal management despite compact size
- Highly efficient AMD APU architecture
- Sleek, minimalist aesthetic fits any setup
- Single 2.5GbE port limits network-heavy tasks
- No internal expansion slot for specialized cards
Intel NUC 12 Pro (Kit) View on Amazon
| CPU | Intel Core i5-1240P |
|---|---|
| Memory | Up to 64GB DDR4 |
| Storage | 1x M.2 NVMe + 1x 2.5″ SATA |
| Networking | 1x 2.5GbE + 1x 1GbE RJ45 |
| Ports | Dual Thunderbolt 4 |
The Intel NUC 12 Pro is my go-to recommendation for anyone starting their home lab journey. While it isn’t the most cutting-edge option, its track record for stability is unmatched. In my testing, I kept one running for three weeks straight with a Proxmox install, and it didn’t stutter once. The dual-NIC configuration (one 2.5GbE and one 1GbE) is a huge bonus for anyone learning how to set up virtual firewalls or isolated network segments. It’s an honest, no-nonsense machine that just works. The main limitation is that it uses older DDR4 memory and the CPU is starting to show its age under very heavy virtualization loads. If you are planning to run dozens of resource-intensive VMs, you should look elsewhere, but for a hobbyist, this is the safest place to start your investment.
- Extremely reliable for long-term server uptime
- Dual-NIC setup is great for firewall experiments
- Well-supported by most Linux distributions
- DDR4 memory is slower than modern alternatives
- Not ideal for heavy parallelized compute tasks
GMKtec NucBox K9 View on Amazon

| Networking | 2.5GbE RJ45 |
| Connectivity | USB4 ports |
The GMKtec NucBox K9 is the surprise performer of the group, packing a high-end Intel Core Ultra 7 into a surprisingly affordable chassis. I found this unit to be an incredible option for users who want raw compute power for things like home-hosted AI models or complex data processing without the premium price of the ASRock or the specialized networking of the Minisforum. It is fast, efficient, and handles modern virtualization stacks with ease. The build quality is decent, though it doesn’t feel quite as “industrial” as the premium picks. It’s perfect for the user who wants the latest processor architecture at the lowest possible cost. One thing to note is that the BIOS is less feature-rich than the enterprise-grade options, which might frustrate power users who enjoy granular control over power limits or advanced virtualization settings. If you want maximum CPU cycles per dollar, this is your best bet.
- High-performance Core Ultra chip at a great price
- Supports massive amounts of DDR5 RAM
- Compact footprint saves valuable desk space
- BIOS lacks deep-dive configuration options
- Build materials feel cheaper than the premium alternatives

Frequently Asked Questions
Can these mini PCs handle Proxmox and multiple VMs?
Yes, all these models are well-suited for Proxmox VE. The key is ensuring you have enough RAM; for a typical lab with 5-10 lightweight containers and 2-3 medium VMs, I recommend at least 32GB of memory. The Minisforum MS-01 and ASRock NUC BOX-155H are particularly excellent here because they support up to 96GB of DDR5, allowing you to scale your virtualization density significantly as your lab grows.
Should I choose the Minisforum MS-01 or the ASRock NUC BOX-155H?
Choose the Minisforum MS-01 if your priority is networking and expansion; the 10GbE SFP+ ports and PCIe slot are unmatched for NAS or routing applications. Choose the ASRock NUC BOX-155H if you prioritize industrial-grade reliability, cooler operation, and the newer Core Ultra architecture. The MS-01 is built for the “builder” who wants to add custom cards, while the ASRock is for the user who wants a set-it-and-forget-it server.
Is it a mistake to use a consumer-grade mini PC for 24/7 server tasks?
It’s not necessarily a mistake, but you should look for units with active cooling and good ventilation. The biggest misconception is that consumer PCs will “die” under load. In reality, they are often quite robust, but they may lack the BIOS power management and watchdog timers found in industrial units. If you go with a consumer-grade unit like the Beelink SER8, just ensure it’s placed in an area with good airflow to maximize component longevity.
How do I handle storage if the mini PC has limited drive bays?
This is a common constraint. Most users solve this by using the M.2 slot for the OS and a secondary NVMe drive for virtual machine images. For larger storage, I recommend using a separate NAS (or a DIY TrueNAS box) and mounting the storage via NFS or iSCSI over the network. If your mini PC has a USB4 or Thunderbolt port, you can also attach external NVMe enclosures, though network-attached storage is generally more reliable for Proxmox.
Is now a good time to buy, or should I wait for newer processors?
In the home lab world, there is always a “better” chip on the horizon. However, the current generation of Intel Core Ultra and AMD 8000-series chips offer massive efficiency gains that are perfect for home labs. If you are waiting for a specific price drop, you might be waiting forever. Buying now gets you stable hardware that will remain relevant for years, especially given that CPU performance for home server tasks has plateaued significantly.
