Three "radiators" (the third one does not know where to place less whether a backup radiator) that would require a little extra explanation for any beginner like me in Raspberry.
Otherwise, after several assembly and disassembly to reach the final constitution of the hull, it still gives an impression of solidity and protection at Raspberry. Transparency gives a nice little side to the machine. When the power plug I bought the same supplier, she returned the first time without the need to DIY for me.
