What exactly would burn the house down? Seriously your backing the other person on here... You have no idea what is safe or isn't in this system. I put it together and i do. I can tell you everthing is fine with it. Everything is mounted and insulated well. So again what exactly do you think would catch fire after the 110v passes through 3 emi and rf filters before the power ever reaches my power supply then i modded that power supply with larger low esr capacitors and the motherboard with larger low esr capacitors. Its only a 500 watt flex atx, and the system doesn't even use all that. Its a very power efficient computer. I didn't put the power sucking components in the system i used something a little on the lower cooler side on purpose cause there is no room in the case for all the heat to go.
