Building on the success of the original manual, this fully revised, updated and expanded second edition brings the reader right up to date with ever-changing technology. The aim remains the same - why buy an off-the-shelf beige box when you can custom design and construct a PC that perfectly fits your needs and your budget? - and ease of understanding is emphasised as we steer the enthusiast through the jargon from motherboard to monitor. In this edition, we have increased the emphasis on data security and thrown a little home entertainment into the mix.
