All in One PC – Pros and Cons


In recent years, the All in one PC is becoming increasingly popular. Coined as AIO, they are seen as a good alternative to a traditional desktop for a number of reasons:

This type of system is very popular with small businesses and home users.

A typical all-in-one pc will begin its life cycle as a barebones system – meaning the case will be empty but contain all necessary components such as motherboard, power supply, graphics card etc. The customer then has the option of choosing their own parts to build up their computer from scratch or using one of many available pre-built turnkey systems. Customizing your own AIO offers great freedom for those who want to create exactly what they need at an affordable price point without additional costs for features they will never use.

All-in-one PC’s are also more environmentally friendly than their traditional counterparts, taking up less of an area on your desk or table and using less energy overall. The smaller size allows them to fit neatly into tight spaces where a tower computer would be too large.

Many people find the all-in-one design attractive and it is also possible to install some mounting hardware on some models, allowing you to mount your LCD monitor on the wall which saves even more space. This brings us to another benefit of AIO systems; cable management. Since everything is integrated into the unit itself there are no cables running around everywhere like with traditional desktop setups (with the exception of power cables).

With careful cable management, it becomes possible to keep the cable spaghetti hidden behind the unit itself, making your workspace look neater and reducing clutter.

There are currently 3 major manufacturers of all in one pc systems;

  1. HP
  2. Lenovo
  3. Apple

These three companies use two types of technology when building AIO’s, either LCD or LED.


LCD screens utilize liquid crystal display technology while LED screens makes use of light emitting diodes. The choice between these two technologies will usually come down to personal preference however there is one distinct difference when it comes to power consumption. When purchasing an AIO you should take into account how much power you use since LED’s uses less than LCDson average around 40-60 watts while the average LCD requires around 60-110 watts.

Aspect Ratio

Aspect Ratio is another thing to consider when purchasing your AIO PC since there are three main types of aspect ratio being used in AIO’s today. The most common type is 16:9 which measures at about 25 degrees, this affects how much vertical and horizontal viewing you will get from an all in one . 4:3 Aspect Ratio displays measure at 20 degree which means that they provide a closer view to the screen than a 16:9 and usually provides more vertical space than a 16:9 display. 22:10 Displays have an aspect ratio similar to widescreen HDTVs so if you watch alot of online streaming videos view websites without scrolling, this may be the display for you.


How to choose the right one?

Choosing an AIO PC is a very personal process and there are many aspects to consider since its function as a PC comes with all of the same considerations as purchasing a regular desktop, such as:

  • CPU Type – You do not want to go too far below your max CPU usage since then it would limit how much you can multitask or run higher end programs. This becomes more important if considering an Intel i3 Processor or less where they lack in performance compared to other CPUs on the market now. When choosing between AMD vs Intel it is good to look at benchmarks from multiple websites , which can help determine what is best suited for your needs, whether that may be streaming high definition video, high resolution gaming or running several programs simultaneously. You can also consider capabilities such as hyper threading which will cut down on the number of CPUs you may need, but generally these are more advanced features that you should be aware of before purchase. However, this means that your system may not be capable of performing all tasks at the same time if overclocked or running powerful non-multitasking programs.
  • CPU (Processor) Clock Speed – This is basically how fast it processes information and usually the higher the better. It is measured in Gigahertz (GHz). The latest AMD Ryzen CPUs have clock speeds ranging from 3-4 GHz, while Intel i3 CPUs range from 2 to 3 GHz . For reference purposes, average computer user does not require a CPU speed higher than 3 GHz.
  • GPU (Graphics Card) Clock Speed – This is the speed at which the GPU processes information, usually measured in MHz. A faster GPU can help with rendering graphics more quickly, especially for high-resolution gaming or video editing. However, if you are not interested in these tasks then there is no need to choose a computer based on its GPU capabilities. Latest AMD GPUs have clock speeds between 1200 and 2000 MHz , while Intel GPUs range from 200-1000 MHz .
  • RAM (Memory) Clock Speed – Memory is basically how much “stuff” your system can store so it runs smoothly when multitasking or when running memory intensive programs such as photo/video editors or games require additional downloads or updates. A high clock speed means your computer can store more “stuff” at once, which makes programs run faster.
  • Processor (CPU) Clock Speed – The processor is the central processing unit of your computer. It is responsible for interpreting and running program code, as well as performing calculations. Processor speeds are measured in GHz or millions of cycles per second, so a 3 GHz processor can process 3 billion instructions every second. A higher GHz value generally means that the processor has a faster speed which allows it to perform multiple tasks without being overwhelmed by too many processes running simultaneously. AMD CPUs have speeds ranging from 1-3 GHZ , whereas Intel CPUs have speeds ranging from 1-3 GHZ .
  • CPU Cache Memory – The cache memory is an area where frequently used program instructions are held for rapid access by the central processing unit (CPU). Having this memory nearby means that there is no need to access more distant memory every time the CPU needs some information. The size of the cache memory determines how much data can be held there for rapid retrieval.

Pros of All in one PC

  • Very slim and sleek design. We have a detailed post about it here.
  • Large screen for multiple purposes (e.g internet, video editing)
  • Most come with a T processor which are very energy efficient.


  • Due to the large screen size it tends not be as mobile as a traditional laptop/PC due to its weight and small battery life
  • Less upgradability. Internal components cannot be changed or upgraded without changing other parts around them also. This can make upgrading the computer extremely costly if the internal components are faulty after extended use. It may even be necessary to buy a completely new all in one PC.
