How easy a job is depends on the person doing it. I consider my self to be pretty damn good with a soldering iron, but I wouldn't touch something so small due to the amount my hands shake, this is how an easy job becomes extremely difficult 
@OP, If you've never picked up a soldering iron before, seek out some professional assistance, you have to think what is the going to cost the most...~£100 for someone to solder on some caps or ~£350 for another 680.

The surface mounting soldering looks fun and I have never tried that before so I may give it a go.
