These are great suggestions, liquid! I think I've now been convinced that the Intellijel 7U is the way to go. That 1U rack frees up more space too. This is the first I've looked into the Black Hole too and oh man, that thing is a beauty. The Erbeverb is real impressive too, but that Black Hole seems to fit with what I'm doing a bit more. Down the road, that Voltage Block looks like the way to go as well.

Thanks so much! I updated my rack a bit based on these suggestions.
