Hi all title says it all. Corsair Carbide 300r no window Worried about spills, and slobber. Keeping it off the baby radar as much as possible.

First can I cover the top portion of the case with a solid material. Say sheet metal and use ventilation out the back. Insead of bottom to top run front to back cooling.

Also MoBo lights anyway to kill those? Dim them? They're like baby beacons. All case lights are dead and fans are variable speed.

Can I dynamat this thing for further vibration/sound deadening?
