  If you want to do this with a card (original poster specified a
motherboard with SCSI built in...), there are two warnings:

1.  The external connector on the 2940UW is an HD68 *wide* connector.
You can spend a lot of money on adapters to connect narrow (SCSI 2)
devices to it.  [This makes the FirePort 40 an attractive
alternative, since its external connector is an HD50.]

2.  Ultra-wide cards tend to have three connectors on them -- 50-pin
and 68-pin internal, and HD50 or HD68 external.  YOU CANNOT USE ALL 3
AT ONCE.  Pick any two.  [Knowing this was not sufficient to prevent
me from (without realizing it) trying it.  It didn't damage anything,
but it didn't work, either.]
