This is a brilliant book for a novice computer builder. I am a Mac user who knows virtually nothing about PCs, so I thought it would be a nice idea to try to build one. This book starts from the very very basics, goes through in detail, every part, it's different kinds and ways that they all fit together. Once you have familirised yourself with all the parts the book then goes through a step by step build of three computers. I would highly recommend this book. The only down side is that all the pictures are black and white, and the quality of some of the pictures is very very poor. Well worth the Amazon price though. I read it from cover to cover, I have now bought all the parts and am ready to build. I will keep the book for reference.
