A mixed EIDE/SCSI system makes a lot of sense; EIDE drives are _much_
cheaper, but SCSI is more flexible, more reliable, and easier to add
stuff to. (I got a tower case so I could add as many drives as I
needed to...) Good luck.

NCR 53C8xx-based PCI SCSI cards are made by a lot of folks (many
`generic' PCI SCSI cards are NCR-based). They're generally cheaper
than Adaptec ISA cards. (under $150 from many sources, under $100
with luck)
For drives and peripherals, look at the Mac magazines and stores;
they understand SCSI a lot better than the PC folks, and you'll
find much better prices.

I don't know specifically about the JAZ, but it is possible to
boot FreeBSD from a SCSI drive on a mixed system. There
are a few tricks (use OS-BS 2.0 to get multi-drive booting,
recompile and re-install the boot blocks so you won't have to
type `hd(0,a)' every time), but it works fine once you get the
various pieces in place.

Win95 has the antisocial habit of erasing boot managers <sigh>; you
may need to re-install the boot manager afterwards.
