End plates? To rack mount it? Unfortunately I don't think there are any for the Snow.
The unit is not rectangular, it's literally more of a trapezoid shape (as shown below). It also has rolled metal edges, there are no obvious ways you would be able to mount it. At 11" at its widest point, it's also much smaller than the 19" width of a rack unit.

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
