Building my own is something I would have done a decade ago, but I've since lost track of what all of the hardware lingo means, or which companies are making decent components.
Desktop hardware hasn't changed much, so if you built a system ten years ago, you'll come up to speed pretty quickly. The main pieces are the same; they just have different features, performance characteristics, and different rules for figuring out which components interoperate. If you want a complete list of parts that will work together, Ars Technica still publishes their system guides regularly.
Compatibility between different parts can seem complicated, but it's simple once you figure out the rules. To be extra safe and avoid accidental incompatibilities between components that should, by spec, be compatible, I always pick components that are popular with builders (measured by the number of reviews on NewEgg) and search the web for mentions of incompatibility between them.
