If you’re in the market for a new desktop PC, it makes sense to consider the new line of mini PCs over a giant tower.

But apart from their serious power in a compact package, there are a few things you should know.

As a recent convert to the world of mini PCs, I often mocked these tiny devices as something which would never hold up to the computing power I needed. But the recent strides in technology have made me realize that the things that make mini PCs small don’t make them any less powerful.

If that sounds like gibberish, here’s a quick explanation of video ports Also, if you are buying a new one, look for a VESA-compatible monitor, in case you want to mount your mini PC on your monitor in the future.

For keyboards and mice: You can’t use an old keyboard or mouse with a PS/2 port.

In fact, make sure you know how much RAM you really need Mini PCs typically support one of two sizes for hard drives: M.2 and 2.5-inch.

The M.2 is only flash storage, while the 2.5-inch format allows for flexibility between an SSD and traditional HDD.

It’s important that you know which one you are buying. However, since battery life isn’t a concern, low power consumption takes a backseat.

M.2 is the new version of what was earlier called “m SATA”. The preferred choice is the 250GB Samsung EVO 850 (0). Even in the laptop world, Intel CPUs typically consume lower power and thus give you better battery life. And recently, AMD’s Radeon-powered laptop processors have stepped it up in the graphics department, out-performing Intel’s offerings in the same price.

The Ready To Go mini PC is ideal for anyone who wants to start afresh.

With Intel NUCs, you’ll mostly get these from third-party vendors like this.

Also, check if your mini PC comes with a mini-HDMI-to-HDMI cable, otherwise you’ll need to buy that.
