I got my lower grill yesterday after only one week. Much better than the 3 weeks for the upper grill.

Taking off the lower grill was a bit harder than the upper as well. I got the upper off with my fingers but I needed a flathead screwdriver to help pry the tabs for the lower. Oh there was also an air deflector that was cake to get off with 7 hex head screws.

After the grill is off there are 4 'sections' of open area. The center are open as that is where the OEM lower grill allows air to flow. The outer 2 are 2/3 blocked by plastic to where the OEM grill inserts tab A into slot B heh. I painted these black.

Over all this was pretty easy to install. It comes with 8 little 'C' type clips that hold the grill in place. Kinda hokey but they seem to do the trick. It also came with 4 1/4 inch push in fasteners that I have no clue what they are supposed to do. They are on my desk, heh.
