Was thinking about, but never tried it before so hesitating as it is a "big thing" to do. (Have a Windows thingy as well, where i had do it once and that meant "Plug n' Pray" 😀 )
Will try resetting the SMC first.
I have a SHARP LCD Projector, as monitor, 160Gb ext Firewire HD (only data no programs) Nikon D100 camera (not permanent) and some speakers connected and wireless connected to the net.
Following software packs:
CS, Nikon Camera Control, Aperture, MS Office, Iwork, FileMaker, Toast, Omnigraf and StuffIt. Plus SKYPE, Itune and a couple of messengers.
No games and fun stuff as its a working machine.
