Temperature and humidity levels are the most important environmental factors to consider when planning the configuration of a data center, as they directly affect the performance, reliability, and energy efficiency of the IT equipment. Excessive heat or moisture can cause overheating, corrosion, condensation, or static electricity, which can damage the hardware and lead to data loss or service disruption. Therefore, data centers need to monitor and control the temperature and humidity levels within the recommended ranges by using various cooling systems, airflow management, and sensors12.

Some electronic items require special e-waste recycling because they contain hazardous materials that can harm the environment and human health if disposed of improperly12. Laptop batteries and CRT monitors are examples of such items.

Laptop batteries are usually made of lithium-ion or nickel-metal hydride, which are both toxic and flammable substances34. If laptop batteries are thrown in the trash, they can leak, catch fire, or explode, causing pollution and injuries5 . Therefore, laptop batteries should be recycled at authorized collection centers or through manufacturer take-back programs .

CRT monitors are old types of display devices that use cathode ray tubes, which are glass tubes that emit electrons to create images on the screen . CRT monitors contain lead, mercury, cadmium, and phosphor, which are all harmful metals that can contaminate the soil, water, and air if dumped in landfills . Therefore, CRT monitors should be recycled at certified e-waste facilities or through retailer or manufacturer trade-in programs .

A dedicated GPU (graphics processing unit) is the most important component for rendering 3-D promotional movies, as it can handle the complex calculations and graphics operations required for creating realistic and high-quality images. A dedicated GPU has its own memory and processor, which are optimized for graphics tasks. A dedicated GPU can also support multiple monitors, high resolutions, and advanced features such as ray tracing12.
