Here is a cool Raspberry Pi B+ or Pi 2 model B case that is LEGO and GoPro mount compatible. The LEGO compatible removable top plate lets your creativity fly. You can remove it to see the Raspberry Pi inside the case. The SmartiPi works the Raspberry Pi B+ or Pi 2 Model B. The three holes in the case align with 75mm VESA mount holes, allowing you to attach this to the back of your monitor. Not too expensive either.
