Good PC book

Can anyone recommend a good upgrade and maintenance book? What about "The Complete PC Upgrade and Maintenance Guide" by Mark Minasi?

Not a book but the PC Guide is a free website that contains oodles of useful information in case that's of any help?

I got that book on recommendation of a friend , found it extremely useful and very comprehensive for what I wanted.easy reading too.
ensure to get the most recent as the one I have would be pretty old in pc terms anyway
