I 2nd the professor messer videos. I first found the link to them on these boards, watched (most of) them, and found them to be very helpful. I also had a large picture file that had all sorts of hardware slots/connections spliced together with their name by each one, each picture very up-close and detailed (the picture file was about 50mb!). Can't seem to find it at the moment... hmm, hope I didn't lose it. I think I got that either on these boards or Rage3d.
