There's some truth in the fact once it's plugged in you're probably good. But I always priotise functionality and user convenience first, so acessing everything while plugged in is a must for me. Certainly could have a wrap-around label with holes in, though, I'll give that some thought! I was just going to go with one on the top side.
The NVRAM was mentioned to me only yesterday, oddly enough. I can certainly accomodate NVRAM load / save as needed. I'm now aware some games use it as a form of protection, I wasn't aware of that before.
