As another year comes to a close, it’s time to remind ourselves that not every tried-and-tested PC hardware tip remains that way forever.

From performance scaling and stability trade-offs to value for money and the role of non-core components, it can be a lot to take in. If you’re building a PC for the first time or re-entering the market after a hiatus, knowing and ignoring these outdated PC hardware rules will probably help you build a better system.
