Why Get a Mini PC?

Mini computers are a compromise between a desktop system and a laptop. You get the expandability and flexibility of the former and the portability of the latter. But why and when should you get one?

Saving space is one of the top reasons why you’d want to buy a mini computer. But then again, a laptop solves the same problem. So compactness shouldn’t be the sole driver for your purchase decision. Instead, look at how you plan to use it.

A small form factor PC is great if you’re looking for a computer to do basic productivity tasks, but don’t need a powerful system to play high-end games or work on large multimedia projects. Activities like browsing the Internet, checking email, or organizing your photo collection are ideal. In the age of work-from-home setups and long-distance learning, mini PCs offer a cheaper, portable and more flexible alternative.

Now, if you’re looking for a gaming mini PC, it certainly is possible. There are models available with mid to high-end graphics cards installed, or at least the ability to add it yourself. However, these machines tend to be expensive and slow. If you’re looking for the best mini gaming PC, it might make more sense just to buy a full-size gaming desktop (for power) or a laptop (for portability).

Things to Consider When Buying a Mini PC

Apart from their size, buying a mini computer isn’t that much different from buying your typical desktop or laptop computer. You’d pretty much look at the same specs, hardware considerations, and features.

How Will You Use It?

Before buying a mini PC (or really, any computer for that matter), you need to figure out why you need it, and how you’ll use it. Specifically, which applications will you be using? Will you be doing light tasks like surfing the web or checking email? Or will you be doing some multimedia work like editing videos or photos?

Virtually all of your purchase decisions will stem from this, so don’t skip this step! The rest of this section will also compare the different specs based on how you’d typically use them.

Note that there are some use cases that are simply not possible (as of the moment) with mini PCs. High-end gaming is one of them, as well as heavy editing or graphics work. So manage your expectations appropriately.

Size

Despite being called mini PCs, there are actually many size subcategories within the mini computer classification. There are, however, no hard or fast rules, as companies have many different interpretations on what constitutes a mini PC.

The smallest mini computers are what’s called “stick PCs”. Because of their small size, however, they’re typically very underpowered and are only ever used for elementary applications like display signage or as a media computer. For even rudimentary casual use, it’s not that suitable.

Next up in size are the NUC PCs, or Next Unit of Computing as Intel calls them. These are Windows-based PCs that are around 5 to 6 inches in size. A lot of them use mobile-oriented processors, making them suitable for light tasks without consuming much power.

Beyond this, you get a broader variety in sizes. You’ll encounter anything from smartphone-sized units to boxes reaching a compact desktop in size and performance.

Size is essential depending on how (and where) you plan to use your mini computer. Suppose you’re aiming for something that you can hook to a TV as a streaming device. In that case, it’s best to get a compact unit that can be tucked behind or underneath your television. If you’re after a laptop alternative, then you can get a little bit bigger in size to give way for better specs

Processor

The processor or CPU is the heart of your mini computer that processes and executes tasks. It’s one of the three major specs that determine how fast your computer is, with the other two being memory and storage (graphics card as well if you’re into playing games).

The CPU is often the most expensive part of a mini-computer, so it’s vital that you pick the right one. With that said, comparing different CPUs can be confusing and complicated, especially for non-tech savvy buyers.

To simplify the process, let’s focus on Intel CPUs for now, because they’re the most popular and widespread in the market.

If you’re planning to do basic productivity tasks like light web browsing or checking your email, a low-end CPU like the Intel Atom or Celeron is more than enough. If you want something a bit more powerful, then you can jump up to Core i3 processors.

For modest gaming, graphics work, or other processor-intensive data-crunching apps, you need something more powerful. Both the Core i5 and i7 can fit the bill quite nicely.

You also need to be aware that Intel CPUs have “mobile” and “desktop” versions of each processor. In Intel chips, you can usually tell this by the last letter of the processor’s number. If you see “T” or “K”, then it’s a desktop CPU. For mobile, it’s “U” or “Y”.

Why is this important? Because, as a rule of thumb, a desktop CPU will be far powerful than a mobile CPU of the same chipset. Mobile processors will be more concerned with the efficient use of battery power. So if you’re a video editor who wants to do work on the go, it’s best to go with the desktop version of the Core i5 instead of the mobile Core i5.

Memory

Your mini PC’s memory dictates things like how many tabs in your browser you can have open at a time, or how many programs you have running simultaneously. If you work with large documents or media files, a large memory is also essential for your computer to keep up.

The minimum you should go for is 8 GB, which allows you to do tasks like handling a reasonable amount of documents and browser windows without showing signs of lag. If you’re a photographer, videographer, or digital artist working with apps like Photoshop, it’s worthwhile to upgrade to 16 GB.

Luckily, memory is inexpensive nowadays, despite having such a significant impact on your mini PC’s performance. You often can quickly expand later on should you need more, at bargain prices.

Storage Size

Storage is, of course, a no-brainer requirement, although it’s not as crucial as it was years ago. As for capacity, it really depends on what you need, but 1 TB is a good starting point. With external hard drives getting cheaper and cloud storage more prevalent, internal storage isn’t that big of a deal anymore compared to years back.

What’s more important is the type of storage you’re getting, since that will impact performance. You have two options here. The traditional hard disk drive features more significant capacities and is cheaper, but is slower and more prone to failure.

The better storage to get is a solid state drive or SSD. SSDs use flash memory technology, allowing them lightning-fast file transfer speeds. You’ll notice that your computer and applications boot up much faster with an SSD. The drawback is that they’re more expensive on a per GB basis.

So bottom line, get a mini PC with an SSD. A capacity of 256 GB should be enough for most users.

Graphics Card

For most mini PCs, a dedicated graphics card is a sort of a luxury. Hence, it’s not as prominent compared to desktops or laptops. Often, what you’ll get is an integrated graphics card that does a fantastic job for basic video playback or light, casual games.

There are some, however, that incorporates a dedicated graphics card. They will give you some graphics muscle and can make your unit into a modest mini gaming PC. Do expect that these mini PCs will be on the bigger size, and they tend to be slower and more expensive.

If you do decide to go with the dedicated graphics card route, make sure your CPU, memory, and storage are up to par (which, sadly, can only further drive the cost up).

Wireless Connectivity

The vast majority of mini computers should already be Wi-Fi capable right out of the box. Look for either Wi-Fi 5 (802.11ac) or WiFI 6 (802.11ax) for the best compatibility with modern wireless networks.

However, a small number are not and require you to purchase a separate dongle or Wi-Fi card to enable wireless connections. Bluetooth support is also nice to be able to support some devices.

Ports and Connections

As with any computer, the vital port is the USB port. Make sure you have enough to allow you to hook up a keyboard, mouse, and an external hard drive at the very least. A good number to aim for is four ports, and they should be distributed in the front and back of the computer for easy access.

For future-proofing your computer, also get one with USB-C ports. A Thunderbolt 3 port and SD card reader are also excellent additions. Only emphasize USB 2.0 ports for backwards compatibility with older devices.

Next, check how you’ll connect a monitor to your mini computer. The bare minimum should be a DisplayPort and HDMI if you plan to connect your computer to your Smart TV. Computer monitors often make use of DV or USB-C. Speaking of monitors, you can also get VESA mounting support so you can attach your mini computer to the back of your monitor – a fantastic space-saving feature.

Fully Configured vs Bare Bones System

Like buying a regular computer, you can get a mini PC in either as a fully configured setup, or a bare bones system.

A fully configured mini PC is ready to be used right out of the box, complete with processors, memory, and all internal components. It has all the cables you’ll ever need, and in most cases even comes bundled with a keyboard and mouse. All that’s required is hook it up to a display, and you’re good to go.

A full setup system is perfect for convenience. Regular, non-tech savvy users will appreciate that it’s easy to use, just like any other consumer product.

A bare bones mini computer is one with only the minimum components installed – usually just a motherboard and wireless connectivity. Before you can use it, you need to add in the missing hardware and install the operating system.

Bare bones systems are ideal for the tech user who wants to have maximum flexibility with their setup. They can combine, use, or even reuse their old components into their new mini PC. Maybe they want to reduce costs or boost performance. Of course, the drawback is that you need to be more hands-on in building it (but then again, some people find the thrill in that).

Noise

Mini PCs tend to be noisier than desktops or laptops in general, and that is due to the internal fan. Because they’re smaller in size, the fan operates more often to help regulate the system’s temperature. Hence, make sure you’re buying a mini PC with a fan noise that you can live with.
