I am preparing to open my Mac + to install 4M RAM (courtesy of chip
merchant, who delivered correct parts on time...) I understand from
reading news that the + uses a linear power supply. Is it possible
to replace it with a switcher? If I do that, then is there enough room
inside the machine (which I have never opened yet) to install a hard
disc drive? There are some very low power drives out there (my conner
3204 for the PC takes about 4 watts for 210MB), so with a switcher I
think I wouldn't need a fan (the + doesn't have one now and has a linear
supply which puts out lots of heat) even with the extra 3-4 watts of a
good HD. I really would like to avoid adding extra things onto, above,
under, behind, in front of, or in the general vicinity of the machine.
Thanx.
