How to Build a Small Gaming PC
3. Opening the Case
Flip over the front panel and remove the two screws holding the optical drive bezel in place (image C). On the front of the chassis, pry off the metal bezel in front of the optical drive tray. Replace the front panel and slide the optical drive into the bay, stopping when it’s flush. Secure with the same M3 screws you used for the SSD.

4. Add the PSU
Unscrew the four thumbscrews securing the PSU backplate. You’ll want as short a PSU as you can get for this: anything longer than 140mm and you’ll have a hard time routing the cables. As tempting as it is to go modular, a nonmodular PSU will be easier to deal with here. Attach the backplate to the PSU and install into the chassis, but don’t put all four thumbscrews back in, as you may want to be able to slide the PSU out later for ease of wiring (image D).

5. CPU and Cooling
Remove the CPU socket protector and install the CPU. Lower the gate arm to secure it (image E). Add the RAM. Although the Prodigy has room for the large skyscraper-style air coolers we like in our builds, those coolers don’t play nice with our solitary PCIe slot, so we’re going with a water cooler.
Thermaltake’s Water 2.0 Performer (catchy!) is an Asetek-built dual-fan 120mm all-in-one cooler that should keep our CPU nice and chilly. But first we have to install the backplate. Find the Intel backplate and assemble it for Socket 1155 per Thermaltake’s instructions. Attach it to the rear of the motherboard. Assemble the retaining clips and screws in the socket ring.
Take the motherboard I/O shield, pop off the tabs covering the Wi-Fi antenna ports, and install it into the case back. Unscrew the case’s 12cm exhaust fan and set it aside. Install the motherboard into the case using four screws (image F).

6. Add the Cooler
Take the all-in-one cooler and one of the 12cm fans, as well as four of the mounting screws and four washers. Run the screws through the washers, through the mounting holes at the back of the case, through the fan (making sure it’s oriented to exhaust out of the case), and into the mounting holes on the radiator. Attach the pump unit to the CPU with the socket ring. Turn to tighten, alternating in an X pattern.
Take the other fan, positioned to blow air through the radiator out of the case just like the first, and install it on the side of the radiator. Plug the fans into the included Y cable and into the CPU_FAN header, and plug the pump unit into the SYS_FAN header near the SATA ports (image G).
