Mini PCs

Our mini PCs swap a full-size tower for a box that sits behind a monitor or tucks onto a shelf, without giving up the CPU, RAM and storage a proper desktop needs.

If you want a quiet, low-power machine for everyday office work, a compact rig for running AI models locally, or a small always-on host for virtual machines, there is a mini PC built for that specific job rather than a single do-everything box trying to cover all three badly.

Buyers come to this lineup for three broadly different reasons, and it is worth being honest about which one describes you before you start comparing specs.

 Most people just want a small, silent replacement for a bulky office tower, and any recent Core i5 or Ryzen 5 model with 16GB of RAM and an NVMe SSD will do that comfortably.

A smaller but fast-growing group wants to run large language models on their own hardware rather than paying per token to a cloud provider, and that changes the shopping list completely, memory bandwidth and total RAM matter far more than CPU clock speed.

A third group wants a small, efficient host for Proxmox, ESXi or Hyper-V, consolidating several always-on services onto one machine that sips power 24 hours a day. We stock ranges built around each of these three jobs.

Explore the range

AI Workstations: compact machines built around unified memory or high-capacity RAM configurations for running LLMs locally with Ollama, LM Studio or llama.cpp, aimed at developers, researchers and small businesses that want AI inference to stay on their own hardware rather than in the cloud.

Hypervisor mini Server/Workstations: small-footprint hosts chosen for their RAM ceiling, multiple NICs and hardware virtualization support, built to run Proxmox, ESXi or Hyper-V reliably as a 24/7 home lab or small-office server.

Buying guide: matching the mini PC to the job

Everyday office and home use. A Core i5 or Ryzen 5 with 16GB of dual-channel RAM and a 512GB NVMe SSD covers browsing, office software, video calls and multiple monitors without hesitation. Look for Wi-Fi 6, at least one USB-C port, and HDMI or DisplayPort if you plan to drive two screens.

Business deployments. Fleets of small-office machines benefit from Windows 11 Pro out of the box, TPM support for modern security policies, and a chassis with VESA mounting so IT can bolt machines to the backs of monitors and keep desks clear. Extended connectivity, including a second Ethernet port or serial connectivity for legacy peripherals, matters more here than raw benchmark scores.

Running AI models locally. The single number that decides what you can run is memory, not the processor. A 7B parameter model needs roughly 16GB of RAM at a comfortable quantization level, 14B models want 32GB or more, and anything in the 32B-plus range needs either a large unified-memory box or a genuine GPU with real VRAM. Fast memory bandwidth and NVMe storage for model files matter as much as the chip itself, so check the RAM ceiling and memory type before comparing CPU cores.

Hosting a hypervisor. Proxmox, ESXi and Hyper-V all need hardware virtualization support (Intel VT-x or AMD-V), and IOMMU support (Intel VT-d or AMD-Vi) if you want to pass a graphics card or NIC through to a specific VM. Beyond that, prioritise RAM capacity over CPU speed, since running four or five VMs is a memory problem before it is a compute problem, and check idle power draw if the box will run continuously.

Brands in this lineup

We source mini PCs from HP, Dell, Lenovo, Apple, Acer and ASUS for mainstream business and home use, alongside specialist compact-form brands such as GMKtec, GEEKOM and MINISFORUM that build machines specifically around high RAM ceilings, multiple NICs and virtualization or AI-focused chipsets. Mainstream vendors suit standard office deployments where warranty and fleet management matter most; the specialist brands tend to win on the RAM capacity and networking that AI and hypervisor buyers actually need.

Who a mini PC suits

A mini PC is the right call if desk space, noise or power draw matter to you, or if you are consolidating several small jobs, browsing, a media server, a couple of VMs, onto one always-on machine instead of running separate boxes. It is the wrong call if you need a discrete GPU with serious VRAM for gaming or heavy 3D rendering, since most mini PC chassis cannot physically fit or cool a full-size graphics card, though a handful of AI-focused models now ship with real GPU silicon built in specifically to get around that limit.

Why buy your mini PC from PonDesk

We source directly from manufacturers and verified distributors rather than reselling whatever is cheapest that week, so the specs on the page match what arrives at your door. Every listing carries clear compatibility notes, and our team can talk through RAM, SSD and networking upgrades before you commit, which matters more with mini PCs than towers since many models are not user-upgradeable after purchase. We ship to the UK, US and beyond, working directly with manufacturers to keep pricing competitive on business and bulk orders.

Are mini PCs powerful enough to replace a full desktop tower?

For most office, browsing and media use, yes, a modern mini PC with a Core i5 or Ryzen 5, 16GB of RAM and an NVMe SSD matches or beats a mid-range tower for everyday tasks. Where towers still win is heavy gaming or GPU-bound rendering work, since most mini PC chassis cannot fit a full-size graphics card.

What is the difference between an AI workstation mini PC and a regular mini PC?

An AI workstation mini PC is built around a much higher RAM ceiling, often 64GB to 128GB, and faster unified memory bandwidth so large language models actually fit and run at usable speed, where a regular office mini PC typically tops out at 16GB to 32GB. The CPU matters less than the memory subsystem for this use case.

Can any mini PC run Proxmox or ESXi?

Most modern mini PCs can install Proxmox if the CPU supports Intel VT-x or AMD-V, but running more than one or two VMs comfortably needs a machine chosen for its RAM ceiling, multiple Ethernet ports and IOMMU support for device passthrough, which is why we list virtualization-focused models separately from general office machines.

Whichever job you are buying for, our team can help you land on the right spec rather than the flashiest one. Browse the AI Workstations range for local AI hardware, or the Hypervisor mini Server/Workstations range for virtualization hosts, and request a quote on any model.
