Kewl. So you didn't do any height adjustments, only lengthened it? I guess for my large screen ones I will do the same. I have been putting it off; afraid to pull the trigger on grinding out the window.
I did on my blue cloupor enclosure and found it too tall, that's how I found out. You can almost see the edge of the physical screen if you really try. It's not a big deal but I knew it could be better so for the mini, I took measurements from the blue. I dremel'd the display window toward the USB connector and just filed off the anodizing on the other side so the opening was uniformly bare aluminum rather than half anodized, half bare. I finished the opening with needle files I picked up from Harbor Freight. I'm very happy with how the mini came out.
