Reactor 4 is named after the Chernobyl reactor that went critical in 1986. The name comes from the fact that the build outputs a significant amount of heat, and my friends joked that I was going to burn my house down with a Vega 64. I used the name ironically for a while but it started to stick, and now over a year after creation, I wouldn't have it any other way.

AMD Ryzen 1700 - All core OC set to 3.8Ghz @ 1.35v VCore
Gskill Trident Z RGB RAM - 16gb 3200 mhz
AMD Radeon Vega 64 Limited Edition - VCore Underclocked to 1520mhz (thermally limited anyway), Undervolted to 1030mV in Pstate 7, HBM2 OC to 1060mhz

Enjoying 1440p ~100+fps, with Freesync in most modern titles on maxed settings (some exceptions like Assassin's Creed), 144fps on games that need it (Rainbow Six, Rocket League, etc). VR runs like a dream.
