What are the best ways to install hardware in a computer case?

2 Mount the motherboard

The motherboard is the main circuit board that connects all the other components, so you want to install it first and carefully. You need to align the motherboard with the back panel of the case, and secure it with screws or standoffs on the mounting holes. Make sure you don't overtighten the screws or damage the board. You also need to install the input/output (I/O) shield that comes with the motherboard, which covers the ports and slots on the back panel and protects them from dust and interference.

4 Install the memory and processor

The memory, also known as random access memory (RAM), is the component that temporarily stores data and instructions for the processor, also known as central processing unit (CPU). You need to install them on the motherboard, in the designated slots or sockets. The memory modules usually have notches that align with the slots, and you need to push them down until they click into place. The processor is the component that performs the calculations and operations for your computer. You need to install it in the socket on the motherboard, and align it with the markings or pins. You also need to apply some thermal paste on top of the processor, and attach a cooling fan or heatsink on top of it.

5 Install the graphics card and other expansion cards

The graphics card, also known as video card or graphics processing unit (GPU), is the component that handles the graphics and video output for your computer. You need to install it in the expansion slot on the motherboard, usually the PCIe x16 slot, and secure it with a screw or latch. You also need to connect the power cables to the PSU and the video cables to the monitor. Other expansion cards are optional components that add functionality or features to your computer, such as sound cards, network cards, or wireless cards. You need to install them in the available expansion slots on the motherboard, and secure them with screws or latches.

6 Connect the cables and test the system

The final step is to connect the cables and test the system. You need to connect the front panel cables from the case to the motherboard, such as the power button, reset button, LED indicators, audio jacks, and USB ports. You also need to connect the fan cables to the motherboard or the PSU, and arrange them neatly with cable ties or velcro straps. You also need to connect the peripherals, such as the keyboard, mouse, speakers, and monitor, to the appropriate ports on the back panel. Once everything is connected, you can plug in the power cord and turn on the system. You should see the BIOS screen or the operating system screen on the monitor, and hear the fans spinning and the drives whirring. If you encounter any problems, you need to troubleshoot them by checking the connections, the components, and the settings.
