Mini PCs aren't a necessity or an option with nearly as much choice as a mid-tower assemble-it-yourself machine when you're out shopping for a computer upgrade. I have one each of a laptop, mini PC, and mid-tower that I use in rotation, and doing so offered a fresh perspective into why you shouldn't dismissively ignore the handful of adorable and tiny computers you can just plug in to fire up. Besides the general readiness to hit the ground running, there are several (albeit niche) use cases where I've found the smaller form factor to excel.

I can already picture some of you reaching for the comments section, but I must state upfront that I'm aware of the obvious compromises a buyer makes on the route to mini PC ownership. For starters, thermal management on a larger chassis is easier, especially for intensive usage like gaming, CGI, renders, etc. Additionally, most mini PCs may not even be up to spec for such tasks. That said, they have advantages.

5 Smaller footprint on my desk

An advantageous limitation

If desk space is at a premium, you might want to consider a unique vertical-style PC case, but they are easy to knock over if you live with particularly enthusiastic pets. That's where mini PCs like the Khadas Mind excel. With a sleek design reminiscent of pocket notebooks, computers like this can stay planted, without ever taking up too much surface area on your desk. This is a particularly convenient option if you often reach for the computer to connect/disconnect peripherals or just want a mobile workstation.

That said, you might have to deal with a thick pile of unsightly cables for which most mid-towers offer cable routing solutions, so they remain out of sight. Another immediate compromise you make for the smaller footprint is the impossibility of leaving the mini PC on the floor. While you could do that with a tower-style chassis and deal with dust inside as a trade-off for a roomy desk, a minuscule PC would be so close to the floor it would double up as a vacuum, choking up its intakes in a short while.

4 Ease of cleaning

This one's for us lazy folks

While we are on the subject of dust and dirt accumulation in computers, it would be remiss not to mention how easily you can clean out a mini PC. With just a can of compressed air and a soft-bristle brush, you can get rid of most of the dust bunnies wedged between the fins around the exhaust. At most, you'll need tweezers to get in between them and pull out the stubborn clumps. In all, it shouldn't take you more than five minutes to dust off even the relatively larger mini PCs.

In comparison, a typical mid-tower has room for around six 120mm fans, a radiator or an air cooler, with the latter adding a couple of more fans, and a ton of nooks and crannies where dust can settle. Most cases today ship with a decent assortment of magnetic mesh filters in front of the fans, but they don't negate the necessity of regular cleaning.

3 Fewer fans, and less noise

Ideal for light tasks

We all love laptops for quiet operation under light workloads, and that's rarely possible with desktops, which have a slight hum from the fans, no matter what your tuning curves look like. Switching the fans off completely is one option, but it is usually untenable for load spikes. In comparison, most mini PCs only have one or two laptop cooling fans in them, and you won't hear them when you're surfing the web or filling up your Amazon shopping wishlist.

The lower fan noise is especially noticeable since the mini PC would likely sit on your desk, a lot closer to you than a typical mid or mini-tower cabinet. Moreover, lower fan noise also translates to fewer unaccounted variables if you prefer using speakers or open-back headphones instead of earbuds while at work.

However, you will enjoy this silence so long as you don't push your machine to the limits. When combating higher internal temperatures, typical desktop coolers can move more air than the smaller fans in a mini PC, meaning the latter has to work much harder to achieve the same degree of cooling. In the process, it might sound like a screaming banshee.

2 Buy a mini PC, get an HTPC for free

So small that you can move it around

I often liken mini PCs and Intel NUCs to laptops without a screen, keyboard, and mouse. You can usually supply your own peripherals, but once you get one of these PCs, it becomes evident that you don't need to stay tethered to the monitor on your desk. The small size and quiet operation of most of the popular small form-factor computers in the market allow you to tuck them into any receptacle on your media console, and the chances that anyone will notice are slim.

If your mini PC is of the dockable kind, like the Khadas Mind and Mind Dock combo, you can happily carry it around so long as you're assured of a display's availability where you plan to use it. With home theaters, that's guaranteed, and most modern PCs, including those running on integrated graphics, don't struggle with 4K media streaming. As such, your tiny computer can be a workhorse by day and a dispenser of entertainment by night.

1 Power is rarely a concern

The epitome of portability

The subject of portability brings me to my favorite thing about a mini PC that trumps conventional machines. You don't need a massive power adapter or a big wall wart to power these computers. Most of them feature power circuitry on the board or inside a smartphone charger-sized adapter. In fact, I often travel with my mini PC instead of a laptop, but I never carry its original power cord along. My machine draws only ~65W at most, which is well within the bounds of multi-output travel chargers rated for up to 120W.

Before you remind me how PC power supplies must cope with transient load spikes, it's worth mentioning that mini PCs are more like laptops than desktops in this regard. Many chargers, like Satechi's models, advertise the capability to power notebooks, so mini PCs shouldn't be an exception.

With such portability, you can comfortably travel with your small computer, and you'll just need to supply a display. Using a keyboard and mouse of your preference instead of a trackpad and laptop keyboard is an added bonus. This is something you simply cannot do with a larger computer, even if you somehow manage to enhance overall portability with a smaller case and such.

Take advantage of the size and simplicity

If your use case can afford the performance tradeoffs a mini PC makes for its diminutive size, you should consider the possibility. After using a smaller computer, you might find specific advantages to the construction that go beyond physical volume and dimensions. In my case, I was happier with the enhanced portability and ease of maintenance, and I haven't missed an HTPC either. Perhaps down the road, when the non-upgradeable internals become a bottleneck, I'll assign this mini PC to NAS or home server duty.
