and your processor is on it.
Check all connections have made been made properly.
Does anything happen at all when you press the Power button?
Check the Front Panel connectors are on the correct pins, or pressing the Power button will do nothing.
Do you have 2 identical sticks of memory installed, as it runs in Dual Channel mode?
Check that any and all jumpers are in their correct positions.
