After looking at the dimensions on the VP150, it wouldn't fit in the side sections of the EC. For the center, I'm going to have to change the shelving a bit, but I think it'll fit with the TV and VCR.

Does the VP150 need any "breathing" space above/below/left/right? If so, how much?

The back will have space so that should be okay. If this final question is answered, I'll move on to the color decision for M22s, VP150 and 2 QS8s for now.
