PC building rules I used to ignore
Some PC building blunders are tough to revisit

If I were building a PC today, there's a lot I'd strive to get right. I'd pick the best CPU and GPU I could within the budget, balance all other components based on performance and value for money, not cheap out on the crucial stuff, and keep esthetics and peripherals in mind. When I was younger, however, I ignored all these best practices, and just went with the cheapest hardware.
