Just assumed you would want to know a good place to get parts. Its also a place to check what kind of price youre looking at. I never used a guide to build my computer, just used the old one as a reference. There should be a place on here somewhere to show how, but I'm relatively new here and dont know where that might be. I'll help look and see what i come up with.
Your motherboard manual is your best bet when putting things together. Each board is different. A guide can give you general assistance, but your mobo manual is your friend.
That is assuming you know what mobo youre getting. I think he was more interested in a general "what's involved" type guide. Some people like to research everything before buying a motherboard. Especially if they dont know what they SHOULD get.
