Yeah these capacitors a big problem. If it's not the actual capacitor itself causing a main board or a power supply to not work, then it's the goo that leaks out and dribbles all over the place causing all kinds of beautiful side issues including electrolysis, pad rot, trace rot, via rot, I/c leg rot. And actual permanent irreversible damage to ICs form the conductive liquid, shortening various legs. Ic's including Ram chips, sound chips, EGRET, CUDA, even resistor packs and VLSI's .
