Compact yet capable, mini-PCs provide desktop-level processing power and connectivity in packages small enough to easily fit on a desk, shelf or bag. Their space-saving designs have made them an appealing alternative for users who still need or prefer the functionality of a desktop but want something with a lighter footprint.
Whether used as a primary or secondary system, mini-PCs deliver the productivity of a full computer without dominating limited work areas. Their portability also allows mini-desktops to seamlessly transition between work and living spaces. Capable of connecting to larger monitors at home while offering mobility around the house or when traveling, mini-PCs provide seamless flexibility that laptops alone cannot match.
Let’s explore 10 important factors to consider when shopping for a mini-desktop computer.
1. Sufficient Processor
The processor, or CPU, is the brain of the mini desktop and determines how quickly it can perform tasks. For general use, like web browsing, word processing, and media streaming, an Intel Celeron or AMD Athlon processor will suffice. However, if you plan to do more intensive tasks like video editing, 3D modeling, or gaming, you’ll want to upgrade to at least an Intel Core i3, i5, or i7 or an AMD Ryzen 3, 5, or 7 processor. Check that the mini-PC you’re considering has a processor that can handle your intended use smoothly without lag or delays.
2. Random Access Memory
RAM (random access memory) allows your computer to multitask by running programs and operations quickly. For basic tasks, aim for at least 4GB of RAM, but 8GB or more is recommended if you’ll be running multiple programs at once or working with large files. Video and photo editing, in particular, are RAM-intensive tasks. Make sure the mini-PC you choose has RAM that can be upgraded later, if needed.
3. Internal Storage
Look for the best mini-desktop that has an adequate amount of internal storage for your needs. Most include at least 128 GB of flash storage, which is sufficient for an operating system and basic programs, but you’ll fill that up quickly if you save lots of documents, photos, videos or games locally. Opt for 256GB or higher, if you can. Also, check if the storage can be upgraded later with an additional SSD or HDD. External storage is another option for expanding space.
4. Connectivity Options
Consider the ports and connectivity options included. Most mini desktop computers have USB Type-A and Type-C ports, an HDMI output, Ethernet networking, and Bluetooth/WiFi capabilities. Make sure the model you choose has the necessary ports to connect peripherals like keyboards, mice, displays, printers, external storage, and networks. Some also have card readers, audio jacks, DisplayPort, and VGA outputs, depending on your needs. WiFi and Bluetooth should be at least ac/5GHz and Bluetooth 4.0/5.0 for best performance.
5. The Integrated Graphics
The integrated graphics chipset in most mini PCs is sufficient for general use but won’t handle intensive 3D games or graphics programs very well. If those are priorities, look for a model with a discrete GPU (graphics processing unit) from AMD or Nvidia that is powerful enough for your tasks. Check benchmarks and reviews to see how different graphics options perform. Otherwise, integrated graphics from Intel will work fine for everyday tasks.
6. Operating System
Most mini PCs come with Windows 10 pre-installed, but some offer options for other systems like Ubuntu Linux, Chrome OS or dual/multi-boot. Consider which OS is best suited to your needs and software requirements. Windows is familiar and compatible with many programs, but it costs extra for a license. Linux is free but has fewer compatible applications. Chrome OS is best for basic web and cloud tasks. Check OS compatibility before buying.
7. Portability Possibilities
If you need a truly portable mini PC to use on the go, carefully considering size and weight is crucial. Some of the smallest mini desktops are compact enough to easily slip into a messenger bag or backpack without adding much bulk.
- Models in the 4-6 inch range and under 2 pounds are ideal for maximum mobility. However, do keep in mind that smaller sizes often mean less powerful components and fewer expansion options to keep things lightweight.
- Larger mini PCs in the 8–10 inch range may still be smaller than a full tower desktop, but the tradeoff is reduced portability. While fine for occasional moving between rooms, their 3-5+ pound weight makes long-term mobile use less practical. Be realistic about how frequently you envision carrying the mini PC with you versus using it stationarily at home or the office.
- Power needs are another important factor for portable use cases. More powerful processors and discrete graphics require beefier power supplies, which result in shorter battery runtimes.
Mini PCs with low-power Celeron or Pentium CPUs paired with integrated graphics can often achieve full workday battery life on a single charge.
8. Expandability and Upgradability
Can the mini desktop be upgraded later if desired? Check if it has open PCIe, M.2, or memory slots that allow adding things like more storage, RAM, or even eGPU enclosures. Some mini PCs have soldered-on components that can’t be changed later. Look for a model that provides expansion options to keep it relevant longer without needing a full replacement.
9. Peripherals Types
What input devices and displays will you use? Check that a mini PC includes or can support the needed connectivity types. Built-in keyboards are rare, but many mini PCs pair well with Bluetooth keyboards and mice. HDMI, DisplayPort or USB-C ports connect to monitors and TVs. Consider the portability and ergonomics of your whole workstation setup, not just the mini PC alone.
10. Warranty and Support
Reputable mini desktop computer brands provide 1-3 year warranties as standard. But check the specifics of what’s covered—just defects, or accidental damage too? What support options exist if issues arise? Phone, email, forums or in-person service centers? Paying a bit more upfront for a quality brand with good support can save money and headaches long-term if problems occur down the road.

Conclusion
When shopping for a mini desktop computer, carefully consider your intended uses, software and connectivity needs, and long-term upgrade or expansion goals. Weigh factors like processor power, RAM quantity, storage size, graphics capability, operating system preference, and included warranty support. Doing your research on the specifications and real-world reviews of different mini PC models will help you select the best compact desktop for your unique requirements and budget. With so many great options available today, a mini PC can be a versatile productivity powerhouse.
