The screwdriver bit to use on these case screws is not named, but I found that my "CR-V 1.2" did the job nicely.

The driver for the screws inside the case are named, as "T5".

On reassembly, I found it hard to reinsert this ribbon cable, so did step 11 again. I disconnected the I/O board, connected the fan and snapped the retainer down on the ribbon cable, then undid step 11 (ie. I connected the I/O board again). As others have said, a brilliant step-by-step guide, and slloeing comments is a great idea too.

On reassembly, it's good to line up the screwhole in the corner of this board with the hole below it, so the fan screw can be replaced properly.
