First Pc that I built, had some major mistakes. I learned a lot about temperature, the meaning of cores, Ghz, and more. I also had some fun with the cable management, it was trash, lol.
The PSU blew up and killed the motherboard and maybe the CPU. Never found out cuz I just sold the factory repaired mobo, the CPU, and the ram as an eBay bundle for about 300 bucks. F. I'll never forget how it was always overheating in the summer. literally made me sweat in my room XD.
I sold my Rx 580 for somewhere around 400 bucks when the mining craze occurred. This was after the first version when Poof.

More to come when I feel like finishing the mk II.
