If you are going to bother shipping boards out and back and paying for work to be done you should replace all the aluminum analytic SMT capacitors on the motherboard. They are all the same age and have the same time usage so they are all going bad. SMT tantalums are easy to spot since they fail shorted (and some tend to explode). Axial eletrolytics tend to be large and last longer, you realy need an in circuit capacitor tester (ESR meter) to see if they need replaced. You need to know some troubleshooting skills to figure out if the MB is the problem or if the power section needs work instead. Then you need to worry has the leaking killed anything else on the board, in that case finding a replacement board is cheaper.
