How To Build The Ultimate Small-Form-Factor Gaming PC
5. Install the Motherboard
By now, you should have your motherboard prepped with a CPU, heatsink, and RAM. Align the I/O ports with the I/O shield and the four mounting holes on the motherboard with the standoffs preinstalled in the case. Secure with screws in each of the standoffs (below).

Now is a good time to connect your 24-pin and 4-pin ATX power connectors (top, below) as well as your front-panel connectors (middle, below). Since space is so limited, keep careful track of your cables. Wrap excess front-panel connectors in twist ties or zip ties and secure them to the bottom of the case (bottom, below). We’ll tidy up the power cables later, but we can take care of the front-panel connectors now.



6. Mount the HDD/SSD

The SG07 can accommodate two 2.5-inch drives and one 3.5-inch drive. With the hard drive cage’s retention bar on the left, slide in the 1TB hard drive so that its power and SATA ports are on the lower left facing you (above) and secure it with the four hard drive screws. Use two SSD screws to attach the SSD to the underside of the drive cage. Before you reinstall the cage, be sure to pull the SATA power cable between where the cage will be and the front wall of the case, then reinstall the cage and connect the SATA power and data cables (below). Because the case is so cramped, you’ll need to use right-angle SATA cables for the SSD and any other 2.5-inch drive you install. The HDD can use a standard cable, like the ones that come with the motherboard.

7. Install the GPU

Unscrew the retention bar holding the PCI slot covers and remove the covers (above). Hold the GPU vertically in line with the slot and press down firmly, aligning the rear of the card with the expansion slots. Replace the retention bar. Take the two PCI-E power cables from the tangle and connect them. Fold the remaining wiring and place it to the right of the GPU, out of the way (below).

8. Install the Optical Drive

We’re almost done! This is one of the trickiest steps, due to the stupid-tiny screws involved. Place the slimline optical drive in the optical drive bay as shown (above). Secure with tiny screws. Connect the SATA adapter cable and attach the 4-pin power connector to the PSU’s 4-pin Molex power connector (below).

9. Wiring and Reassembly
Now is a good time to tidy up your wiring. Every cable from the PSU should be attached to something: The 24-pin and 4-pin ATX power cables should be attached to the motherboard, the two PCI-E power cables should be plugged into the GPU, the SATA power cable should be connected to the SSD and HDD, and the 4-pin Molex cable should be attached to the optical drive’s power cable. Use twist ties or zip ties to secure cabling (below).

Remount the optical drive tray using the four screws you removed in the first step. Connect the 18cm fan’s cable to the motherboard (below) and reinstall the top fan enclosure, reversing the process from the first step.

One last thing: Because of the intake-fan placement on our GPU, we’re going to want to rotate the SG07’s side-panel window and vent. Use a 2.5mm hex-head screwdriver to reverse the orientation of the side panel (below). Reinstall the case cover. Connect your keyboard, mouse, monitor, and speakers. All set!

Here we're removing and re-orienting the SG07 side-panel window to accomodate the fan on our GPU.

Packed with Power

Onboard Wi-Fi It means never having to say, “Could you find me a 100-foot Ethernet cable?”
CPU Cooler Though we used the stock cooler, the SG07/Zotac combo can accommodate several coolers, like the Thermaltake Slim X3 and Prolimatech Samuel 17.
Wiring Believe it or not, this is a pretty cleanly wired case. The SATA cords are secured to a tie-down beneath the hard drive cage.

Airflow A two-speed 18cm intake fan keeps the SG07’s internals well-ventilated.
