I love the original design but thought access to the MicroUSB port, SD card, and reset button would come in handy. Moederbeer says that the case is designed to be mounted vertically, so a hole lets debris in, which makes sense but sometimes this is still needed. So I made a hole and a cover for it, and also covers for the wire inlets, because you may not use all of them and then it's useful to be able to cover them as well.
To be honest access to the SD card only works with a pair of pliers (push it in to release with your finger, then gently pull it out with pliers, and to insert use the reverse order). To make this really accessible would require a much larger hole due to the distance the board is set back from the wall of the enclosure. Not a biggie for me.
