Setting up your Mac

[obliterations]

OK, I just bought a:

Apple G5 Power Mac Desktop Computer
(Dual 2GHz, 512MB RAM, 160GB HD with SuperDrive)
(Im picking it up today, but the monitor wont be here for a week)


I've been running OS9 for years on a Lonbard Power book (XLR8ed to G4) and I wanna get with the times. I havent had a lot of cash, so this has been a difficult move.

Since I dont have the $$ to upgrade and add a media drive (just yet), I will be stuck partitoning the one it comes with. I will be using Logic Audio 7.
So heres my question...

How much drive space do I need for the "System" partition?

I have to admit I havent used OSX, so Im not familiar with the best way to partition out the drive. I "Think" the System partition should hold all the software like "Peak" and "Logic 7" Or is it best to create a partion to hold the Apps And another partion to hold the System software?

Any tips you may have to help things run better would be great.

...And yes I know Ram is going to be the first thing I wanna add to this machine.

Thanks!
