MOTM

Open frame? Okay, I don't understand. How can you fit more than 19" wide of
modules in a 19" rack? In the Tardis, it works, but in my universe....

It wouldn't be a 19" rack, then, would it? If you're talking about moving
the vertical rails farther apart, then you're talking about a non-standard
rack... not something you would mount your digital delay or your
Expressionist over your modules on, not something supported by any existing
hardware. I already have two tall 19" racks in my studio and I've already
opted not to mount my MOTM in those kinds of rails... I know I wouldn't
consider a non-standard rack.

I don't know if Paul's rack rails are flat or angled. I never wanted to go
the rack route since day 1, so I'm waiting for the flat rails.

What I'm talking about using 19" rails as horizontal beams leaving space is
that the rails are L-shaped in cross section, but not a clean "L". There is
almost always a 1/2" or 5/8" "round" to the joint because of the thickness
of the metal used in the rails. Stamping, tapping, and bending the rails is
far cheaper than extruding a clean "L" and then tapping, so that's what you
get. When you sandwich multiple rails together, the rounds leave a wide
space between module rows.

Buying those screws seems trivial... until you want them in black. Not a
Home Depot item. Obviously SOMEONE carries them, but many on the list here
have expressed frustration getting exactly the right screw.
