First PC build. Used for gaming, coding, and other standard use.
Coming into this project, I knew next to nothing about PCs. Went straight to mini ITX for aesthetics, even with the possibility of cable management/assembly issues. Assembly had no problems - Metallic Gear case is great. Cable management, however, became a nightmare once all the extra hubs were added for the fans (RGB hub, Lighting Node Pro, 1-to-8 PWM Fan Hub).
Functional build went smoothly, the worst parts were adding fans and RGB. I fried the case RGB by plugging in the connector the wrong way, and my motherboard only has 2 fan connectors. I ended up needing to buy extra parts way after finishing the actual "build".
Assembled parts over a few months, built the PC, then kept slowly accumulating more parts and peripherals. Still learning a lot about what's good and bad, right and wrong, but it works and I made it, so I'm happy!
