What would happen if I don't replace the PS? Would the computer blow up or something? Can I get any old power supply, or do I need a certain one for this tower?
It likely wouldn't blow up, but it might not boot, run sluggish or constantly restart itself when trying to draw power that isn't available. Typically it will be the first since power usage is highest at boot. You will need a power supply that will fit into the tower and make sure it has the correct output connectors for your harddrive (to make things easier).
