Eddie,

If you re-read my posts in this thread, all along I have been suggesting mixing in the single box but using a hardware control surface. I still stick to this as the least trouble free option. You can even do this with a crappy motherboard based soundcard and it will have less noise issues than what you will introduce through the out to mixer to a different computer system you are building.

However, I realize that doesn't involve as much sleuthing and soldering and wiring that this will involve which might ruin some of the fun.
