Big update. The case is pretty much done, just need to attach the handles and cut the window panel. I got a local powder coater to take a look at it, he qouted me $60 for everything (strip prep spray bake). I'm probably going with Black Wrinkle.
Here's a size comparison with my R4
Here's it next to my friends 350D
And more pics
Hopefully custom length cables soon, really need them lol.
