This is what I did. I got the Spacelas PT-30K scanners and was looking at the soundcard dac route but ended up going with the Flashback3/Quickshow set up.
This is what I did too. The PT-30K's are working great and QS (I'm running the V2 beta) is pretty sweet.
I stuck it all in a pelican case and have been having a blast with it. Just have 532 at the moment, but now want to build an rgb.
