Overkill PC for my uses, mostly RPG games like The Witcher, some FPS like Destiny or DOOM, etc. But I'm a hobbyist and a perfectionist, so the upgrades just kind of snuck up on me.
All PSU cables made from scratch. Added some simple mods like painting the witcher signs on the AIO fans, and an acrylic panel at the bottom to mask the light bleed. My favorite, of course, is the witcher medallion on the pump housing.
