I built my own computer from advice gleaned on this site. All the members were really helpful and supportive!
I haven't read the files, but here's a question, do you already subscribe to the magazine? If not save yourself some money on the monthly magazine by subscribing online or by phone or post, and choose the PC Advisor Issue Archive CD as a freebie! This way you get the How to Build Your Own PC (2001 version) aswell.
