Emachine, I have two for my kids. It is common for the psu to blow these mobo's they are 4 years old. The first I am rebuilding because it blew out. My son's I am replacing the psu before this happens. I put in a thermaltake 430w. It is a little bigger size than the one I pulled however it does fit. The rear fan has some room against my dvd player but not as much as the old one.1- Is this a major problem? 2-Should I go with the kind where you only plug in the wires you need so as to leave more open space when I replace the one I'm rebuilding for my daughter?
