4. Step-by-Step Assembly Instructions
Step 1: Prepare the Case
Remove side panels
Install standoffs for the motherboard
Plan cable routing
Step 2: Install CPU
Open motherboard CPU socket
Align CPU with socket (triangle marking)
Secure CPU carefully
Step 3: Install RAM
Open DIMM slots
Insert RAM sticks until they click
Use dual-channel slots for best performance
Step 4: Install Motherboard
Place motherboard on standoffs
Secure with screws
Ensure alignment with I/O shield
Step 5: Install GPU
Insert GPU into PCIe x16 slot
Secure with screws
Connect power cables from PSU
Step 6: Storage Installation
Mount SSD in M.2 slot or 2.5″ bay
Connect HDD if available
Step 7: Connect PSU & Cables
24-pin motherboard power
8-pin CPU power
GPU power cables
SATA power for drives
Front panel connectors (USB, power, reset)
Step 8: Install Cooling System
Air cooler: Mount on CPU, attach fan
AIO liquid cooler: Install radiator, connect pump
Apply thermal paste if needed
Step 9: Cable Management
Use cable ties
Route cables behind motherboard tray
Keep airflow unobstructed
5. BIOS Setup & OS Installation
Power on PC → Enter BIOS (Del/F2 key)
Enable XMP for RAM speed
Set boot drive (SSD)
Install OS (Windows 11, Linux, or dual-boot)
