If you are looking to take your Computer Kit apart to rebuild, follow these steps!
Remove any cables and anything inserted into the USB ports from your kit.
Place the Computer Kit flat on a level surface, with the ethernet and USB ports on the left hand side.
Gentle squeeze the right side of the casing and gentle wiggle the case to release the Raspberry Pi and the top casing (which could be your speaker!)
If you're left handed, simply spin the Computer Kit round, so the ethernet and USB ports are on the right side and gently squeeze the left side of the case.
