over the years I have installed harddrives, video cards, updated ram, changed powersupplies and thought this would be very easy. everything has changed it feels like I have never done anything. between work and everything else that gets in the way its a pretty hard job for me. worried about burning out my quadro 4000. I am going to change the power supply to the Corsair AX Series and also going to change my 4gb x 4 ram to 8gb x2 incase I want to add more later on.
