Good info, Art. The timing was nice, because just an hour or two ago I finally got around to at least putting the sump in the stand and taking a close look at clearances and component sizes. I think I'm going to have to give up on my idea of that Hydor 200w in-line heater. It needs to be both out of water and vertical, and it's a full 12" long. I've got a spare Ebo-Jaeger 200w and Hydor 150w. I'll probably use one of them.
Since I've gone with the HOB fuge, I do have more in sump options than before. I'm thinking now I'll use the center section for media reactors.
Still waiting to see more details about that Euro-Reef skimmer.
