hi, I made a case that was low profile for the rpi B version, but it allows access to the GPIO pins and everything, just like as if you didnt have a case, so plates/shields fit on it perfectly and are still usable. I know you can access the GPIO on the normal RPi B pibow version, but you need a cable, this one, you dont. This one is more for people who do the electronics and such, or just want a cool looking case.
here's a pic, there's more on my thingiverse page with the design files that you can just print out.
It's the one I use now, and everyone loves the look of it, even more so than my other cases that Ive bought in the past.
