Buying Guide

With the advancement of science and technology today, the current mini PCs sets are able to carry the most advanced technologies, not inferior to the conventional computer sets. Shrinking a bulky desktop computer about the size of a book, it can even be put in your pocket, or carried as a USB is seemingly impossible. However, mini computers are designed with micro components so you can shrink your workstation or gaming PC for easy carrying while still ensuring the performance as a normal computer.

Inside the compact, aesthetic design, the mini computer cases also contain an unexpected power. 2021 is over, past the time when massive computers weighing tens of kilograms can meet working productivity, or satisfy the needs of young people to play games. In this era, you can experience the power of a workstation in a small mini-computer with a notebook or even have products just like a USB. Despite the ability to efficiently process work at lightning speed, the mini PC still has some limitations compared to conventional computers, although it is not significant.

After all, if you need a computer that you can carry with you that can easily fit in your backpack, or even put it in your pocket, the mini PC is still the right choice for you.


1. Are Mini Gaming PC’s good?

Yes, just like their ‘normal’ counterparts, these mini PCs can game with the best of them, and sometimes even surpass the quality of full-on desktop computers.

2. How long do mini PCs last? 

The reply completely depends on the type of programs, the required settings, and the specified determination. On the off chance that you’re a competitive first individual shooter who requests the highest resolution and settings, a rig might last more than 3 years.
