How to Build an Awesome Gaming PC for $647
3. Install the Memory
Installing memory is relatively simple but requires more force to install than most components. For that reason, we typically recommend installing the RAM when the motherboard is on a flat surface, before it’s in the PC. It’s a good idea to lay the mobo on the plastic bag or foam lining that it shipped in to protect it from shock. To install the RAM, make sure the retention clips are in their fully unlocked position, then line up the notch in the RAM module with the keyed part of the slot (image A). When it’s lined up properly, follow the guides on the side of the slot to gently slide the module into place, applying even pressure across the top of the module. Finally, make sure that the retention clips are locked in place (image B). Repeat the process for the second module.

4. Mount the Mobo
Next, you’ll need to mount the motherboard in the case. Before you slide it in, check the back of the ATX backplane connector and make sure that any excess pieces of metal won’t block your ports. This is a fairly common rookie oversight that requires almost complete disassembly of the PC to fix, so you don’t want to miss it. If you find any obstructions, simply fold them up into the inside edge of the case.

After that, it’s time to carefully lower the motherboard into the case (image A). Make sure your ports line up with the holes in the ATX backplane, and double-check that there are motherboard standoffs behind all the mounting holes on your motherboard. Once you’re sure everything is good, you can start screwing down the board using the screws that came with the case (image B). We recommend starting in one corner, then screwing down the opposite corner, and working around the board until everything is locked in place. It’s important that you don’t overtighten—using too much force can damage your motherboard.

Finally, you’ll need to connect the front-panel headers (image C). Consult the motherboard manual to find the exact location of the front-panel power, reset, and light connectors. The power and reset switches don’t require a particular orientation, but the lights do—as a general rule, the colored wires are positive, while the white wires are negative. You should also connect the USB header and front-panel audio cables now, as well. They’re clearly labeled on the board and keyed to only work in the proper orientation, so it’s difficult to mess this up.
