HI,
Can someone give me the Cliff Notes version of opening the M0001 case? I
removed the five screws from the back (including the two deeply recessed
screws) but the case is just as tight as when the screws were in. What am
I missing?
Thanks...Win

I can only base my knowledge on a the Mac Plus as that;s the closest to a M0001
I've worked on (in my case to wire in fans to help ventilate the hot air).
If I remember rightly, there are 5 large Torx 15 screws, as you say, 2 under the handle
(the deep recessed ones), two at the bottom on either side, and one behind the battery
flap.
Once the large Torx retaining screws are out the back should just slide off but they can
take a bit of persuading. Apple techs used to use a 'case cracker' to pull them
away but
seldom can you even find one never mind use one these days. My method usually involves
getting
a fir grip on the lid and giving it a light tug away from the main assembly.
BE CAREFUL. You want to lift it straight up and not to either side as you might damage
the tube or the analogue electronics board. Don't 'pick it up and shake it'
either as when
it gives the fall could cause damage to the plastics or worse the tube.
Usual caveats apply during removal and once the cover is off - mind the tube and analogue
electronics - they can have stored charge that will give you a fair whack if you touch it
(yes and in some rare circumstances can be life threatening yadayada crossing the road is
dangerous etc.).
How easy it comes of depends wether it's been removed many times before. First time
removals
can be tight as hell.
Might I ask why you are removing the case bucket?

you need a case popper. Get what I believe is called a spring clamp from a hardware store
or Home Depot, Lowes. etc. It's like a steel clothes pin on steroids. Typically they
have orange rubber on the handles, bigger ones are bright green. You get it in the space
between the 2 case halves and pry them apart. It might mar the case a bit (it's been
over 15 years since I cracked a Mac I think). Oi kids.

I'd urge you to try and do it without metal implements if you can - the case is likely
to be more brittle than it was when new. I've handled a lot of aging Apple hardware
over the years and their case plastic wasn't usually the best with age. Not exacly
falling apart but prone to edges chipping and cracking, especially on the analogue board
side where it gets very warm during operation. Of course the majority of my work was done
one SE/30s and Mac II/Mac Quadra era stuff which used the later platinum plastics which
ere not as robust as the beige plastics.

I'd urge you to try and do it without metal implements if you can
C: True metal should be avoided if possible. 2 peeps could try doing it together. One
person clamp on the back half, and the other dig their nails into the opening (shorter
stronger naiils would be best. My nails, though grow fast, are always bending. Which is
why I have to keep them very short. Ouch). You could walk around a Home Depot or
equivalent and see what you can find that's say plastic and rigid enough to pry it
apart. I don't see you necessarily having a lot of luck though. If you're careful
and work slooooow (minimize force/acceleration), you might even be able to do it w/o
marring the plastic or cracking, which I guess could be a good point to mention. You could
also think about wrapping the ends of the clamp w/something, perhaps even notebook paper
(thin and likely to lessen the probability of marring). In any event you can work slow and
say start at the bottom of the case, pry a bit (you don't necessarily need to see a
lot of movement from
the getgo) then go to the top, and repeat.

As far as I know, theree are only 5 screws vixible, but jsut to check,
there are 2 receisd in the handle,. one at each end of the connector
panel, and one unde the battery cover.
With those out the case will be tight. There is a special 'Mac Cracker'
tool that has 2 wide flat blades. It fits i nthe gab between the case and
the front bezel, and theh squeezign the handles of the tool separates hte
blads and forces the case apart.
I've never used one. What I do is put the machine face down, grip the
case firmly, and press on the battery amd the connectors. In the end it
comes free.

Never needed any sort of tool for opening compact Macs.
Put the Mac face-down on a folded towel. Whack the sides of the back casing with both
hands simultaneously. The case halves separate with a satisfying PLOP.
