Yes. A reasonably powerful PC with at least two nice fast IDE drives
should do the trick. I recommend you buy such a machine, set up
postgres, and start experimenting. It will probably take a couple

efficiently.

Right. You may find it worthwhile to drop the indexes, import, and rebuild
instead of import with the indexes in place, if you're not doing queries
at the same time. Or maybe partial indexes could help....
