Everyone mentions the obvious PC building mistakes new builders should be aware of. Stuff like breadboarding, motherboard standoffs, PSU orientation, and removing the peel from coolers and heatsinks is important, but most builders know it by now. There are, however, other PC building and maintenance mistakes that you’re probably still making. These mistakes can limit your PC’s performance, lead to overheating, tarnish your gaming experience, and even reduce component lifespan. Some of them are linked to conventional wisdom, while others are tied to ignorance. You may not even know that some of the items on this list are mistakes, per se, but fortunately, it’s pretty easy to fix them once you get to know about them.
