Instructions

1. Step 1

Take out side of case by unscrewing two mounting screws on back or side. Drape all interior wiring over side of case to keep it out of way as you build.

2. Step 2

Install motherboard to inside of case. Line already drilled holes in motherboard up with brass standoffs already in case. If there are no brass standoffs, hand-tighten them into position, ensuring they align with motherboard's mounting holes. Do not over-tighten the mounting screws.

3. Step 3

Attach power supply at back of case. Ensure all cables are long sufficient to reach different parts inside case. Attach 24-pin ATX connector to appropriate area on motherboard.

4. Step 4

Softly put CPU in socket a clip retaining brackets down around it. Firmly press heat sink/fan (HSF) on top of CPU and push on every of four mounting "pins" until they click through motherboard. Tug softly up on HSF to make sure a tight mount.

5. Step 5

Install DDR2 by clicking into DIMM slots. If motherboard has color implied DIMMs, ensure RAM installed in similar colored slots.

6. Step 6

Install the graphics card in PCIe slot and ensure latch on right side of slot locks into place. Attach appropriate power adapter to back or side of card. If you are using an on-board graphics chip, you may skip this step.

7. Step 7

Take out plastic bezel on front of case and slide optical drive back until it is flush with front of case. Connect mounting screws to sides of drive inside case. Attach appropriate cables to back of optical drive. If you are using an IDE cable, be sure to check jumper settings of drive and ensure it is set to "master."

8. Step 8
