Haven't played with video on the mac for ages but here goes. All current
macs have firewire included and come with iMovie for free, which I've heard
good things about (especially for a free editing program).

No current mac uses SCSI. They dropped SCSI completely a few years ago.
Internally, it's the same IDE bus that you'll find on a PC. Externally, it's
the same USB and Firewire connectors, so the only concern for those devices
is drivers to make them work with the system. As for ram, again, it's the
same stuff used by PC's. I just recently dropped an extra 256mb of pc-133
into my 3 year old G3, works fine.

Haven't done any majour video capture in awhile, so I can't really comment.
The biggest determination here though is the speed of your drives. If you're
concerned about video capture then SCSI or Firewire drives are the way to
go. While UDMA-100 IDE drives may give a good speed on paper, IDE is still
very dependant on the CPU. SCSI and Firewire are far less CPU intensive, so
you'll see better video capture speeds since the CPU is freed up to deal
with the data, instead of the drives. I suspect this may be why you found
you needed a hardware encoder card to be added, that moves the encoding off
the CPU, which lets the CPU just contend with shuffling data around.
