From Stephen Bigelow, the #1 author in PC hardware, comes a handy, step-by-step pocket reference to building your own customized PC. He explains in easy-to-follow detail how to choose your components, assemble them quickly and efficiently, test the system, troubleshoot, take advantage of upgrades, and install your operating system.
A little bit dated considering technologies now exist that aren't mentioned in the book (USB 3, SSD drives, etc.) but an excellent book for older machine repair.
