For laptops and all-in-one PCs, people look for the plenty of storage space and the latest processor. While selecting between different desktops and all-in-one PCs, you need to look for major specifications like processor, memory, hard drive, graphics card, optical drive, operating system, form factor, and so on.
Businesses are widely adopting all-in-one PCs because they have a single box that acts as both, computer and monitor. All-in-one PCs have the advantage that there is no need of a separate display cord. On the contrary, desktops consist of a computer case along with a separate monitor. So, does it mean that all-in-one PCs are better than desktops? Actually not. Both have their own set of advantages. Desktops are smaller in size with less heat generating components. Depending upon your requirements, you can pick the one which fulfills all your criteria.
All in one computers are just a style of desktop computer system. They still have the same requirements in terms of features and function. The only difference is the number of components. All-in-ones have a single box that is the display and computer versus the desktop that is comprised of the computer case and a separate monitor.
This gives the all-in-one computer system a smaller overall profile than a desktop computer system.
The all-in-one PC still has an advantage over these systems in the number of required cables. Since the monitor is integrated into the system, there is not a need for a monitor cable or separate display power cord. This reduces the clutter on, underneath or behind a desk.
Buying a desktop does have some distinct advantages over an all-in-one PC though. Due to their small sizes and need for lower power and less heat generating components, many all-in-one PCs feature mobile designed components including processors, memory and drives. All of these help make the all-in-one small but they also hinder the overall performance of the system.
Another issue that all-in-one computers have is their upgradability. While most desktop computer cases can be easily opened by the consumer to install replacements or upgrades, all-in-one systems tend to restrict access to the components due to their small nature. This typically only limits the systems to having their memory upgraded. With the rise of high speed external peripheral connectors such as USB 3.0 and Thunderbolt, internal upgrade options are not as critical as they once were but still make a huge difference when it comes to some components such as the graphics processor although external graphics units could change this.
