Check over the inside of the unit to ensure that no wires are sticking out of place. Wires along the sides of the unit should be properly routed into their own retention clips to avert any risk of damage. Wires should not be loose or slack at any location, as they are of a precise length to reach their respective components when properly installed.

Confirm that all of the motherboard connectors are fully seated. Each connector should be of the appropriate length to reach its intended plug, and due to the size and location of each connector, there is little chance of ambiguity in connecting these.

Confirm that the power switch on the motherboard is towards the left side, as shown, and that the power switch slider on the top of the case is in the same direction (off).
