I keep getting that question, based on that I guess I should be more worried lol. I didnt think it was anything to worry about.  To be honest it was what seemed easiest to me, Im pretty decent at making things outta wood and never really tried using metal. I was also concerned about ESD, I dont like the idea of uncoated metal being so close to my mother board and the gpus sitting on it. Idk I'm questioning now if metal is an upgrade I want to make
