I'm turning 30 this year, love building PC's and Programming... and was a nerd before it was cool.
In general I prefer AMD > Intel/Nvidia but I got to admin that Vega was a disappointment. My favourite brands are Nocuta, beQuiet! and Asus. For RAM I prefer G.Skill, SSD Samsung or Crucial. I do not use HDD anymore in general since I do not store much files (clouds OP).
I'm from germany and studying IT Security beside my full time job.
I like to use different cases and to try different brands. It would be cool to make a review channel and get some sponsoring but I'm pretty sure this won't happen.
