The feet look just like the ones in the brochure for the standard all-in-one version, 55N and 55T. I'll post a few more photos this weekend. The bottom feet, CY4109, give it better stability, but the back feet, CY4108, are kind of useless since they are for lying the unit flat, and the connectors coming out of the back of the meter bridge unit wouldn't clear unless you put it up on blocks.
I did not find any side panels for it. I was contemplating making some of my own out of some nice hardwood, or having some made, but have grown to like the cast aluminum "tech" look, so I think I'll leave it like this. I got some of those Darklab NAB hubs in matt silver that match well.
Do you have the manuals?
Photos to be posted as soon as I get a moment to take them.
