I put a 4GB ide in mine and I did partition it, in fact I formatted it
on my beige g3 with 8.6.
(8.1 can tolerate that, but System7 may not)

Mine has 1 because it only has one slot. Some have two but not all.
you can also use a 128 in the one slot, the other takes a max 64MB and
it must be one-sided.

About the motherboard, yes you can upgrade to ppc (I wouldn't swear to
the specific number tho w/out checking).
Some people have said here that you may need to upgrade the power
supply also. I believe there was an upgrade card which would not need
that. You should research these things carefully before you buy (sites
such as Low End Mac can help).
Probably the RAM of 192 is max, it is only more if you have the one-
sided before.
For ethernet I have a card in the LC slot. (the card is called an LCII
(like but not same as in MacII) )
The main problem I have with mine is that the sound is not stereo and
it is not cd quality. however the cd does play in stereo full quality
through the headphone jack (cd drive has built in analog output). Too
bad with the extra RAM it could record nicely with a big drive. My
powerbook 540 has stereo both ways but lack play through and short on
RAM (same era). Oh, well. Maybe though a powerpc would help all that.
I haven't the TV card so I can't comment on that.
