My first gaming pc. Upgraded from my ****** laptop. Had a great time building.
CPU: Needed to match it to my needs. I will be video editing on this computer so I knew I needed a beefier processor, and the 4670k matched my budget. I wanted an unlocked cpu so I could overclock if I wanted too. I have tried, but I rolled an unlucky cpu in the chip roulette. I literally cant push it past 4.0 ghz with jacking the vcore to obscenity high levels. But I figure overclocking right now would be beating the dead horse anyway.
GPU: I knew I'd be going with a AMD card from the beginning. I had originally started planning for this build early October 2013, and was waiting for the funding to come through. At the time I was going to go with the 7950, but then the r9 series was announced, and the 280x came out at a competitive $300. It seemed like a no brainer.
Case: I like the style of the Phantom and NZXT products in general. The full tower design was a breeze to build in. Loads (I mean LOADS) of cable management room. The side panel window gives me nice look at all the pretty computer guts. And it helps that it's fire engine red. If you hadn't noticed I was going for a color scheme.
Motherboard: It had everything that I needed from a motherboard. Overclocking support, x16 pcie, enough sata connections, usb 3.0. But it honestly had me at the dragon heat sinks. Those are just ridicules. The dragons is where I got the inspiration for the name of the computer. Also red. My only gripe is that MSI put a ******* blue led over the bios switch. Afterwords I realized that a Asus mobo would also look nice as hell, and support Intel Turbo Boost, which the gd65 doesn't (in attempts to push their OC Genii on people.) But the gd65 does come with a nice audio chip set.
RAM: Pretty basic. I knew I wouldn't need blazing fast RAM for a gaming rig. 8gb is perfectly enough for now. I may need to upgrade in the future though. Also red.
PSU: Yes. I know. This power supply is heinous overkill. For whatever reason I was possessed to buy this PSU. Not that there's anything wrong with it, just that it doesn't quite match my build. Both in color and watts.
Storage: SSDs just absolutely blow my mind. It probably made the biggest difference in feel between this and my laptop. 15 second boot times, just everything about it runs great. I was happy that I forked over the extra money for the 500gb. More then enough room to hold the OS and games.
CPU Cooler: The Hyper 212 Evo is cheap and effective. Not too much here, I just didn't want to deal with the stock Intel Cooler.
Fans: Oh god the fans. I have one of the Prolimatechs intake on the front, intake on the side, and exhausting on the back. Then one of the nzxt 140mm intake on the front (hidden completely) and 200mm exhausting on the top. All of them are plugged into the fan controller. And my god are the LOUD. Okay it's not too bad, only ~56db from about 2 feet away. Only on high, which I only use for gaming, and I'm under headphones anyway. It's tolerable on medium.
Edit: Add an HDD for all the video and got a mechanical keyboard.
