Just wanted to pass on this constantly updated PC Building Guide from Nortichardware.com
Between this awesome guide and the many others out there, I wonder if we should get a sticky going with nothing but PC building guides.
No offence to DdogG, but those helpful links havent been updated since 05'
Anyway, you link to the guide:
PC Building Guide
It is basic to a point, and gives you a good start on what you need to consider so you can do more in depth research yourself.
Enjoy................................
