Monitor controls, though I use the remote.
Power supply and extra HD holder it failed to boot the other HD! I didn't really need it so removed it later.
Internal VGA connector
Mini VGA connector
The mess is hidden :) but easy access and dismantling was required.
OSX running on the external mini VGA socket worked fine. But the internal VGA failed to run because it seems locked into 72 Hz and the LCD reported an error.
A big thanks to Leo Bodnar, with out his excellent how tos my emac would still be a very heavy paper weight
