Good start. I'm interested to hear your review compared to a regular ported box.

Yes, more input from you as soon as you can. Are you going to get it playing today?

With all these BP builds coming of late, I'm getting more and more eager to build mine...

That's a tease! Especially, because it appears to be all hooked up.
