8" disassembled pics. I'll post measurements up this evening. Click each pic for a larger version.
Pretty easy to take apart - 4 screws for the back of the case, small tabs in the top to pop out (just like the 7", it sounds like), ribbon cables, etc. The 4-wire connector on the side is for the touchscreen and is a ***** to disconnect. The 2-wire on the other side is a little tough to get to with big fat fingers.
