CPU Cooler: Maintains optimal CPU temperatures. Depending on your CPU and usage, opt for an air cooler or a liquid cooling solution.

Memory (RAM): Temporary storage for active tasks. For most users, 16GB is sufficient, but 32GB or more may be beneficial for intensive applications.

Storage:

• Solid State Drive (SSD): Offers fast boot and load times.
• Hard Disk Drive (HDD): Provides larger storage capacity at a lower cost, suitable for storing large files.

Graphics Processing Unit (GPU): Handles rendering of images and videos. Essential for gaming and graphic-intensive tasks. Ensure compatibility with your motherboard and case.

Operating System (OS): Software that manages hardware and software resources. Common choices include Windows, Linux, or macOS (for Hackintosh builds).

Peripherals:

• Monitor: Displays visual output.
• Keyboard and Mouse: Input devices for user interaction.
• Speakers or Headphones: For audio output.

Cables and Accessories:

• Power Cables: Usually included with the PSU.
• Data Cables: Such as SATA cables for storage devices.
• Cable Management Tools: Like zip ties or Velcro straps to organize cables neatly.

Tools for Assembly:

• Screwdrivers: Typically a Phillips-head screwdriver is needed.
• Anti-static Wrist Strap: To prevent static discharge that could damage components.
• Thermal Paste: Applied between the CPU and cooler to enhance heat transfer; some coolers come with thermal paste pre-applied.

Networking Equipment: Routers, switches, and hubs that facilitate data transmission across networks.

Storage Devices: Hard drives, solid-state drives, and network-attached storage for data storage and retrieval.

End-User Devices: Desktops, laptops, tablets, and smartphones used by individuals to access IT systems.
