Not much to say, an RX 570 (AORUS) and a 1080p 75hz monitor (AOC) for gaming. The Ryzen 7 1700 (not overclocked yet) for my work and video editing.
A red and black color scheme: RAM with red LED, RGB motherboard, RGB stock cooler on the Ryzen 7 1700, RGB mouse, 8 colours LED keyboard, red&black monitor, black GPU&backplate, black case&case fans and black PSU.
I used a minimalistic case, with decent I/O to which I added a wireless adapter (don't roast, I can't pull ethernet cables) and it has 2 stock case fans (no red LED fans yet).
