Also I have 2 more USB 2.0 ports in my keyboards so four is enough.
1.25GHz PowerPC G4
512MB PC3200 SDRAM
32MB ATI Radeon 9200
40GB Ultra ATA hard drive
Combo drive (DVD/CD-RW)
DVI/VGA video output
Built-in ethernet card, soundcard and speaker (although I am using my 4.1 Logitech).
Will make an external USB/Firewire HD and DVD-RW from my internal HD and DVD-RW. The transition felt bizzare at first but now I know I did the right thing. Programs fly despite heavy multi-tasking.
