Also consider that you might want to use multiple sound card inputs.  It's
trivially easy to add sound ports to a computer using USB devices.  I've got
a home audio setup that has four such USB devices powering audio zones.  I
use two of the line-in inputs to re-route other external signals.  The
re-routing is sometimes a bit tricky as it involves redigitizing the
signals.  On an 'old school' sound card it was possible to keep the analog
signal and simply re-route it out.  But as soon as you get into moving the
signals off one device and out another it's requires the CPU be involved to
process it.

The upside to multiple inputs is the ability to record from them all
simultaneously, provided you've got enough CPU and storage.

Just a thought to consider.
