Dead in the water

Just when I thought things were looking up...

I plugged in my USB thumb drive today to format it, and upon ejecting the volume my machine had a kernel panic. Seeing how I cannot power on my machine until I receive a new top case, I'm effectively dead in the water for getting any real work done this weekend. I hope Apple chose a really bloody fast shipping option to get my part in, because I'm really sick of waiting to return to normal.
