This is probably just idle curiosity considering my financial situation, but I'm a little confused about how people with outboard converters typically interface with their computers. I realize that a lot of people have "legacy" interfaces that have converters and pres, and put their outboard converters through these. But say you are designing a a system from scratch. Most of the converters I've seen aren't designed to interface directly with a typical computer. Do you get a PCI interface? Something else?
