In fact, the caps will ruin your motherboard faster if you never turn it on. Aluminium electrolytic capacitors should be charged up once a year, or the foil will start to degrade, performance will suffer, and they will eventually leak acid which will eat away any copper in the surroundings..
So my advice is to either have them recapped and start using them, or sell them to someone who will.
