Much better pics, sailpog.
As saltynay said, you can try hiding those cathodes. Maybe the cathode at the left, can be put at the top. And the bottom cathode, more closer to the edge.
Try stuffing that snake cluster, behind the 5.25" drive cage. If possible, turn the hard drives around....they really make a difference.
But with the side panel on, you don't see much of the wires anyway.
