Might sound weird, but after I build my first keyboard, I saw a slight boost in my gaming performance. Might have been a placebo effect, but it was definitely a lot better playing on my custom than on my Ducky. I'm about to start school soon, so I can only imagine that using my custom keyboards is going to be way nicer than on a prebuilt. I wish I could bring my keyboard into work, but they won't let me bring outside keyboards into work :/
