- It’s often easier to do this before the motherboard goes into the case.
d. Attach the Motherboard to the Case
- Set the motherboard inside the case, aligning it with standoffs.
- Secure it with screws.
e. Install Storage Drives (SSD/HDD)
- Mount storage drives in their designated trays.
- Secure and slide them into place.
- Connect power and data cables.
f. Install the Graphics Card
- Insert the graphics card into the motherboard’s PCIe slot.
- Secure it to the case with screws.
g. Connect Power and Data Cables
- Attach the power cables from the PSU to the motherboard, CPU, GPU, and storage.
- Connect the data cables (SATA) for drives as needed.
h. Install Cooling Systems
- Attach case fans and CPU cooler.
- Plug the fan connectors into the appropriate motherboard headers.
- If using a liquid cooler, follow the manufacturer’s installation guide.
i. Double-Check All Connections
- Make sure every cable is attached snugly.
- Check for loose screws or cables that might block fans.
j. Close Up the Case
- Put the side panels back on.
- Stand the case upright.
5. Powering On and BIOS Setup
