This assumes, though, that the capacitors on that replacement motherboard 
are of reasonable qulaity. Personally, I'd probably replace the 
capacitors anyway on any second-hand motherboard before they caused any 
problems. A handful of electrolytics are a lot cheaper than the time 
wasted and hassle casued if the machien fails at the wrong moment.
