iBook 600+Mbox=what can I expect?

[LALOMIR]

Hi!
My question is what can I expect for the following configuration plus the MBox (I'm planning purchasing one of these)
iBook
CPU: G3 600Mhz
Memory: 384 Mb. RAM
HDD: 20GB
CD-RW and DVD
I'm a singer who works mostly with midi and a couple of audio track at once, no more than that. After that mixing process I attempt to mastering onto two tracks with software. That's it!! I mean: compression, channel strip (EQ), reverb. Please any info. is welcome here!!!
PD: I had switch from PC almost 3 months now, (before the apple ads!), so please give a hand, because it's all new for me (for god, actually)
