This build began with the purchase of a GTX 970 in January 2015 in order to run the Oculus Rift DK2 on my previous PC, which was starting to show its age at six years old. Originally I went with the Antec Twelve Hundred case and Dark Rock Pro 3 CPU cooler, but I wasn't happy with that build, as the cooler barely fit and the case didn't offer much space for radiators. I ended up upgrading to the Phanteks Enthoo Primo case and Swiftech H320 AIO water cooler, and am much happier with them. The case came with five 140mm fans, and the water cooler with three 120mm fans. I've increased this to six 140mm fans and eight 120mm fans, bringing the total fan count to fourteen. I use two PWM splitters to connect them all to the motherboard.
I didn't have a color scheme in mind originally, but when I realized that the case and motherboard matched with their black/white look, I decided to roll with it. In service of this, I soldered replacement white LEDs onto the video cards to replace their stock blue LEDs, and upgraded to individually sleeved black/white CableMod PSU cables.
At first I was going to stick with the monitors from my previous build, but then I stumbled across a very good package deal for two GTX 970's and QNIX 2710 monitors. I pulled the trigger, and bought the triple monitor stand, SLI bridge, and third monitor to complete the build, configured together to effectively become one 49" display with a resolution of 4320x2560@120hz.
QNIX 2710 DVI-only models, for those who aren't familiar, use A- grade Samsung panels sloppily thrown into the cheapest housings QNIX can get their hands on. They and others like them are the cheapest way of obtaining 27" 2K panels, and as an added benefit they can be overclocked to 110-120hz without dropped frames or other issues. Unfortunately the housings are ugly with large bezels. I resolved this issue by following two guides on Overclock.net to remove the housings, paint the display panels' aluminum frames matte black, and epoxy the PCB boxes with their VESA mounts directly onto the back of the panels. This dropped the bezel size by half an inch and looks much better.
In the future I'll probably switch the video cards to water cooling, as the top two cards have poor airflow and run pretty hot. The Swiftech H320 pump should be capable of handling one or two cards in addition to the CPU, but I'll likely add a second pump and radiator and split the three cards between those and the H320. I also plan on adding three fans to the top radiator for a push/pull configuration, and am considering replacing the Phanteks manufacturer badge with one of a custom design.
