All-in-One PC from the company HP. The EliteOne 870 G9 model features a 27" screen with a resolution of 2560x1440. This particular screen size is ideal for most use cases, providing a middle-ground solution that will satisfy both work and entertainment needs, such as watching movies, videos, etc. It also features an IPS Panel. IPS screens offer vibrant colors, wide viewing angles (the image does not distort much when viewed from the side), and are energy-efficient. They are suitable for video and image editing.
The touch screen is a significant aid in professions related to reception, medical clinics, education, photography and video studios, elderly care centers, etc. Additionally, Windows 11 Pro is designed to fully utilize touch screens, especially when viewing photos, browsing, and drawing. 

It incorporates the Intel Core i5-13500 processor clocked at 2 GHz. This is a powerful processor and is ideal for work conditions that require multiple applications and browser windows to be open simultaneously. It can run programs like Photoshop, Premiere, etc., without issues. 

It has 16GB of DDR5 RAM, capable of supporting the processor in all demanding tasks. 

It is equipped with a 512GB SSD. This capacity is sufficient for the operating system, additional programs beyond the basics, and storing a considerable amount of photos, videos, etc. If it fills up, there is the option to purchase an external hard drive, as well as the option to replace the existing internal drive with one of larger capacity. 

An all-in-one computer has every component that a traditional desktop computer has, such as a processor, hard drive, memory, etc., integrated into its screen. It operates in the same way as a traditional computer but usually has a smaller profile, offers higher aesthetics, and takes up much less space. It is also easier to move than a traditional desktop computer.
Its upgrade capabilities are limited only to replacing the RAM and storage space. Finally, it is not aimed at gamers as it does not have a powerful graphics card, with very few exceptions, which still do not approach the performance of the cards available in traditional gaming desktop computers.
