I have been building pc's since 1994 and have never run it to this problem. so people I have a brand new CM Stacker 830 and I have put 2 power supplys and 3 mother boards in it and none will boot even with all outside acessories (usb audio 1394) unplugged reset and power wires unplugged short the power terms take the screws off the board and hold it away from the hold off screws. and the psu's and mother boards work fine in other cases. Cooler Master support will not email me back. its a 279.00 dollar door stop!!! any thoughts?
