Yup. My first build all I did was make sure that the parts I ordered had connectors that matched my MoBo, bought em, then put it together pretty much without looking at manuals. Only looked at a manual once, and that was to set the jumpers on the MoBo. I was right at 13 or 14 when I did it, and my computer still works. Making a new one so I can actually game and whatnot (my computer can hardly manage Fable, and can't do Spore at all) but 4 years for a comp isn't so bad.
