This is a shot just to give you an idea of placement of the shield. The holes will be patched and it will be painted. for cooling of this section a intake fan will be places in the front before the HD and the 2 fan PSU will carry any hot air out the back. Before it's asked... yes the HD cage is going on the bottom.

I cut out the front section so I can make a clean install of a 120mm fan.

This is the cut out for the fan mount. The next few pics are of my great dremel skills.

These are 2 shots of the mounting plate installed and the fans in place.
