Absolutley on the sound card + Memory IMHO.  Build or look for a moderate 
box...bare bones boxes with Athalon XP 2500 go for around $350 - $400 with 
512Mb DDR 2700 included. That would include a 50Gig 7200 rpm ATA 133 HD which 
is sufficient for most stuff. But even if budget is restricted to a P3 or 
such...buy more memory and a GOOD sound card. The ice1712 M-Audio series seem 
to do well. I have a Delta 1010LT and I'm very happy with it. it was $180.00 
used from Ebay.

USB is not well supported.  Cross talk is not a big deal unless you are 
looking at perfection!!  I get some xtalk on my Delta 1010LT I suspect 
because of the poorly shielded RCA connectors...but it's not enough to ruin 
anything I've recorded.

Standard disks do just fine. 7200 rpm ATA 133 drives do what you need from 
what I've seen. Seems the type of filesystem and how well your box is "tuned" 
are far more significant than the drive itself.
