If you're equipped and trained to solder SMD (surface mount
devices, T I N Y stuff), it's easy. There will be the rare individual who has the equipment and/or know-how, but they're rare.
I dabble in PC overclocking, there are some very skilled solderers there (and here, in the
mods subforums) who can do it. I'm not bad at soldering, but no way am I able to reliably solder SMD's. I've ruined a good PC motherboard trying, after successfully soldering two others.
