I'm pretty sure that the AMD.com one should be just fine. I think I used the same one last year. I was building a socket based system but the howto was a slotA system howto. OH well, same thing really. If you understand computers half decent and you have an idea of what goes where and in what order, then you should be fine. You always got general hardware forum
This is the order that I fallow;
motherboard jumpers
processor ATTACH THE HEATSINK!!!!
ram
video card
(notice I haven't put anything in the case yet)
hook up the power supply and fire it up, if it posts, then continue putting it in the case.
Put that crap in the case now
screw some sh!t in
hook up the drives
screw everything up
install OS of your choice.
I don't actually fallow that exactly, but it's a rough outline.. seeing as how I'm not in the situation right now, I probably missed a few things.
